4 01TE HIWIN Cossed Rolle eaings (CR Seies) Intoduction HIWIN Cossed Rolle eaings consist mainly of an oute ing, an inne ing and a pluality of olles and spaces. The olles lie between the inne ing and the oute ing. The space is placed between olles to pevent the mutual fiction so as to decease the toque esistance fo otation. In addition, the suface of the olle and the olling tack is linea contact. So, when the beaing is loaded, the loading aea will be vey lage. Thus, the elastic defomation will be less, and the beaing will achieve longe sevice life. Each olle in a Cossed Rolle eaing is cossed at a 90 angle, which is able to handle the loading foce fom multiple diections at the same time. HIWIN offes the following six types of Cossed Rolle eaings defined by the following as the split oute ing type (CRA), the split inne ing type (CR), the high igidity type (CRC), the split oute ing with mounting holes (CRD), the high igidity with mounting holes (CRE) and the customized type (CRX). The split oute ing type is suitable fo otating the inne ing. The split inne ing type is suitable fo otating the oute ing. The high igidity type is suitable fo otating both the inne ing and oute ing. The mounting holes could be used to aid in the assembly. The customized type could be modified to meet the custome equiements. Cossed Rolle eaings possess high igidity and high otational accuacy, which could be widely used in industial automation contol, obotics, machine tools, inspection and medical devices.

Equation (2) can be used to calculate the basic life ating unde a constant load and a constant evolution: L= ( C ) P (2) In equation (2), L is the basic life ating of the beaing in 10 6 evolutions; P is the dynamic equivalent load; C is the basic dynamic load ating; and the unit of P and C should be the same in eithe Newton (N) o kilogam foce (kgf).

11 8 01TE Static Equivalent Load, P 0 When the beaing expeiences a adial load, axial load and toque, the pemanent defomation will take place at the contact location of the olle and the tack. This load is efeed to as the static equivalent load, which can be calculated using equation (3): P 0 =F + 2M D pw F a... (3) In equation (3), P 0 is the static equivalent load; F is the adial load; F a is the axial load; the unit of P 0, F and F a should be the same in eithe N o kgf; M is the toque in N mm o kgf mm, the foce unit should be the same as P 0, F and F a ; the pitch cicle diamete, D PW = (inside diamete of beaing, d + outside diamete of beaing, D)/2, and the unit is mm. Safety Facto, f S The safety facto (f S ) is detemined by the basic static load ating (C 0 ) and the static equivalent load (P 0 ), as shown in equation (4). The suggested safety facto based on the beaings opeation condition is shown in Table 9: F s = ( C 0 P 0 )...

If the axial load (F a ), the adial load (F ) and the toque (M) ae applied on the beaing, no diection should be consideed fo these thee loads because they ae all positive values N = kgf = lbs; 1 mm = inch. Recommended fit Table 10 Suggested toleance of shaft and beaing housing Cleaance Suggested fit Load condition type Shaft eaing housing Rotation load of Common load h5 H6 C8 inne ing High vibating load (0~5 µm of intefeence fit) (0~10 µm of intefeence fit) Rotation load of Common load g5 JS6 o J6 oute ing High vibating load (0~10 µm of intefeence fit) (0~5 µm of intefeence fit) Rotation load of Common load js5 o j5 H6 C1 inne ing High vibating load k5 JS6 o J6 Rotation load of Common load g5 JS6 o J6 oute ing High vibating load h5 K6 Note: 1. When the beaing has a highe peload, the fitting way in paentheses should be used. Example 1: The axial cleaance class is C8, the inne ing is otated (oute ing is not otated), the split oute ing type (CRA) is suggested. Cleaance fit (H6) Intefeence fit (h5) eaing housing Shaft Example 2: The axial cleaance class is C8, the oute ing is otated (inne ing is not otated), the split oute ing type (CR) is suggested. Intefeence fit (JS6/J6) Cleaance fit (g5) eaing housing How to fix the beaing and the design of the backet and mounting disc Shaft The backet and the mounting disc ae pats fo suppoting and clamping the beaing. The Cossed Rolle eaing has a thin wall, so it is necessay to conside the igidity of both the backet and the mounting disc. When the split type of beaing is used, and the igidity of both the backet and the mounting disc is insufficient, the beaing will be defomed due to uneven pessue of the inne ing and oute ing, esulting in educed pefomance and stability. In ode to pevent this occuence, the backet and mounting disc should be designed as follows: Housing: The wall thickness of the backet, T, can be calculated by equation (5): T> D-d x (5) 2 In equation (5), D is the outside diamete of the oute ing; d is the inside diamete of the inne ing. Steel is the mateial used fo the backet in this equation. If aluminum o aluminum alloy is used, it should be adjusted in accodance with the popety of that mateial.

13 10 01TE In addition, scew holes can be added into the backet. So, when the beaing needs to be emoved, the bolts can be used to eject the beaing fom the backet without damaging the beaing. As fo the dimension of the Mounting disc(da, da), please efe to the elevant dimension shown in the beaing specification. Mounting disc: The wall thickness (E) and the cleaance (S) of the mounting disc can be calculated by equation (6). E = x 0.5 ~ x 1.2 H = (6) S = 0.5mm Refe to Table 11 fo the numbe of bolts used fo the oute ing mounting disc. If the inne ing mounting disc is used, the inside diamete of the beaings inne ing can be substituted into Table 11 fo calculating the numbe of bolts. If medium had steel is used fo the backet o the mounting disc, the toque value shown in Table 12 can be used fo tightening the bolts. Additionally, the dimensional toleance of the pats should be consideed while installing the mounting disc in ode to make the mounting disc and the inne and oute ing combined closely. T Use bolt to eject beaing Use bolt to eject beaing Fo high accuacy demand, mounting disc ae designed with a section diffeence which can be used to adjust the tightening foce by ginding the section suface. Mounting disc made of steel ae suggested to design with a 0.02~0.05mm section diffeence, futhemoe, mounting disc with lage axle diamete o load should have lage section diffeence to povide sufficient lock igidity.

Inspect the pats befoe installing: Clean beaing backet, main axle o othe pats to emove dit o gease. 2. Place the beaing into the beaing backet and main axle: To match the design cleaance, keep the beaing hoizontal and inset the beaing into the beaing backet o axle. If it is had to install, use a ubbe hamme to slightly hit evenly aound the peipheal of the beaing in axial diection. So that the beaing can be inseted into the beaing backet o axle easily.pay close attention to the hitting foce as the beaing could be damaged if the foce is too lage. Aftewads, the matching status of Installation sequence

14 01TE beaing and datum alignment can be examined by checking if thee is noise detected due to misalignment. Fo an intefeence fit, use heating o cooling to expand o shink the pats fo ease of installation. e sue the beaing tempeatue does not exceed 80. If the split inne o oute ing is acentic, please loosen the bolts slightly and otate the monolithic ing to adjust the concenticity of split ing, so that the beaing can be fit in the backet. 3. Install the mounting disc: Place the mounting disc onto the beaing and align the scew holes. Scew all the bolts in the holes fist and follow the ode as shown in above diagam when tightening bolts in diagonally opposite sequence. Do not tighten bolts at once. Othe Infomation Lubication 1. Thee is #2 Lithium/Calcium soap gease lubicant in all Cossed Rolle eaings. Deliveed beaings can be used immediately as diected. If thee is insufficient lubication, the fictional esistance will incease and the sevice life will be educed. The lubicant should be supplemented fo the open beaing peiodically, appoximately evey 1 ~ 6 months. The lubicating fequency depends on the application condition. The lubicant should be distibuted evenly inside the beaing. 2. Avoid coss-mixing lubicants. 3. If the beaing is used in high vibation, clean oom, vacuum, high o low tempeatue applications, a specific lubicant should be used, please contact HIWIN. Allowable RPM The allowable DN value of the Cossed Rolle eaing is mm pm. If the CR WW C8 P5 beaing is used, it has a olle PCD of 65 mm. So, the allowable pm is about 60000/65 = 923 pm. Cautions 1. The nomal opeating tempeatue of the beaing is 10 ~ 80. If it is ove this tempeatue ange, please contact HIWIN. 2. If a foeign substance entes inside the beaing stuctue, the otation oute of the olle may be damaged, o the beaing may fail. 3. If a foeign substance entes inside the beaing stuctue, please clean it then efill the lubicant. 4. Please do not emove o apply foce to the bolt and nut of the split beaing.
