13 Track Capacity Allowable otational Speed Track capacity is defined as a load which can be continuously applied on a Cam Follower placed on a steel track surface without causing any deformation or indentation on the track surface when the of the Cam Follower makes contact with the mating track surface (plane). The track capacities shown in Tables.,.2 and. are applicable when the hardness of the mating track surface is HC (Tensile strength /2). When the hardness of the mating track surface differs from HC, the track capacity is obtained by multiplying the value by the track capacity factor shown in Table. If lubrication between the and the mating track surface is insufficient, seizure and/or wear may occur depending on the application. Therefore, attention must be paid to lubrication and surface roughness of the mating track especially for high-speed rotations such as cam mechanisms.

If the tightening torque is too large, it is possible that the threaded portion of the stud will be broken. When there is a possibility of loosening, a special nut such as a lock nut, spring washer, or self-locking nut should be used.

Precaution for use The maximum allowable load on Cam Follower with C-Lube Unit is, % of the maximum allowable load of the needle bearing. C-Lube Unit may be damaged and influenced to the smooth roatation and lubricating performance by excessive load. 2 After assemling C-Lube Unit and in the machine, please confirm that C-Lube unit provides oil correctly to the track surface before actual operation. Do not use in the environment which contamination of liquid and/or harmful foreign matter are expected. Do not wash with organic solvent and/or white kerosene, which have the ability of removing fat nor leave them in contact with the above agents. To ensure normal rotation of the Cam Follower, apply a load of % or over of the dynamic at use. Also, the needs to be rotate over a revolution to supply lubricant on entire outer diameter surface. eplace with new C-Lube Unit when inside oil finishes completely. e-lubrication is not possible. 7 Do not apply a load onto the C-Lube Unit directly. In case loosening of the nut is predicted due to vibration, using lock nut, spring washer and other special washer are recoended. =.2kgf=.22lbs. =.7inch

41 Track Capacity Allowable otational Speed Track capacity is defined as the load that can be continuously applied on a oller Follower placed on a steel track surface without causing deformation and indentation on the track surface when the of the oller Follower makes contact with the mating track surface (plane). The track capacities shown in Tables. and.2 are applicable when the hardness of the mating track surface is HC (Tensile strength / 2 ). When the hardness of the mating track surface differs from HC, the track capacity is Table. Track capacity (Metric series) Separable oller Followers AST ()AST oller Followers with crowned on-separable oller Followers AT AT Cylindrical oller Followers Track capacity Identification number AST ()AST obtained by multiplying the value by the track capacity factor shown in Table. If lubrication between the and the mating track surface is insufficient, seizure and/or wear may occur depending on the application. Therefore, pay attention to lubrication and surface roughness of the mating track especially in the case of high-speed rotation such as for cam mechanisms. Track capacity 2 oller Followers with cylindrical Identification number 2 AST ZZ Track capacity Identification number Track capacity unit: The allowable rotational speed of oller Followers is affected by mounting and operating conditions.

Table dn values of oller Followers Type Cylindrical oller Follower Lubricant Grease 2 72 Oil 7 2 In case of oller Followers without an inner ring, the shaft requires heat treatment and grinding finish. The recoended surface hardness of the shaft is HC, and the recoended roughness of the shaft is.2 m a or less. Also, the and cage are guided by side surfaces of the mounting parts. Therefore, it is recoended that the side surfaces of the mounting parts be finished by grinding or at least by machining. (See Fig..)
