1 Precautions for Use Features Seals for Neele Roller Bearings have a low sectional height an consist of a sheet metal ring an special synthetic ruer. As these seals are manufacture to the same sectional height as Neele Roller Bearings, grease leakage an the penetration of foreign particles can e effectively prevente y fitting them irectly to the sies of cominale earings shown in the imension tale. When fitting seals to neele roller earings with inner ring, wie inner rings (see page H2) must e use, as shown in the mounting examples. Ientification Numer The ientification numer of Seals for Neele Roller Bearings consists of a moel coe an imensions. An example of an ientification numer is shown as follows. Example of ientification numer Moel coe imensions S For the single lip type, the lip has to face inwar when using the seal to prevent grease leakage, an outwar to prevent the penetration of foreign particles. The S type of oule-lips is effective for prevention of grease leakage an ust penetration. However, when the main purpose is to prevent grease leakage, the main lip shoul face inwar, an when use mainly to prevent ust penetration, it shoul face outwar. 2 The permissile temperature range is For use at higher or lower temperatures, a special seal is require. Please contact for further information. The limiting peripheral spee of shaft epens on the conitions of use, ut is normally to 8 m/s. oule this spee is possile if the conitions (lurication, temperature, shaft finish, etc.) are goo. Mounting Types Seals for Neele Roller Bearings are availale as shown in Tale. Tale Seal type Type Single lip oule lips Type of seal 20mm Outsie of seal 28mm With of seal mm When inserting the shaft, amage to the lip shoul e prevente y chamfering the en of the shaft, as shown in the upper part of Fig.. When this cannot e performe, a mounting ushing shoul e use, as shown in the lower part of Fig.. When press fitting the seal to the housing, o not strike it irectly, ut fit it gently, using a suitale tool. To prevent early wear an heat generation at the seal surface, it is necessary to thickly coat the tip of the lip for the type, or to fill the space etween the two lips for the S type, with earing grease.
