Product Details

Description

The sheave and sheave are typical application examples for the Double Row Full Complement Cylindrical Roller Bearing D 20-85mm. Since the outer ring is narrow, no additional sleeves or spacers are needed. The two snap ring grooves on the outer ring simplify the bearing configuration of the pulley. For better corrosion protection, the bearings are also supplied with a special anti-corrosion coating SQ171. A black oxide coating can also be achieved to optimize the tribological properties of the bearing. In addition, the bearings can be manufactured to the clearance and tolerance levels of the particular application.

Feature

Its maximum radial load carrying capacity is achieved by a fully compensated design, ie the maximum number of rollers is installed in the available cross section. They are suitable for low to medium speeds and can withstand axial and tilting moments in both directions. To prevent dust and splashing water from entering the bearing. The bearings are fitted with contact seals on both sides, and special greases allow the bearings to operate under extreme conditions. Lubrication holes on the outer and inner rings can be easily relubricated through the shaft and housing.
