Ship Rudder Shafts Taper Roller Bearing / Sealed Tapered Roller Bearing

china 30205 bearing manufacturer

Product description

This 30205 25x52x16.25 taper wheel bearing supports high radial loads and axial loads in one direction between a rotating and non-rotating member. The tapered roller bearing is formed by combining a cone (inner ring assembly) and a cup (outer ring). It has a 7,800 revolutions per minute (RPM) limit with grease lubrication, and a 10,000 RPM limit with oil lubrication.


Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
