1.Spherical Roller Bearing Information:

Roller 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 roller bearings are open, shielded,

or sealed.Sealed bearings are lubriexcavatored with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubriexcavatored in place,

with periodic reappliexcavatorion of lubriexcavatorion, 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.

2.Appliexcavatorion:

agricultural machinery to conveying equipment,

robotics,

dental equipment,

elevators,

rolling mills,

ship rudder shafts,

and aggregate crushers,

among others.

3.Features:

Support radial and oscillating axial loads

C3 radial clearance allows thermal expansion for continuous operating temperatures up to 200 degrees C/392 degrees

Tapered bore with 1:12 taper for compensating for a flexing shaft or fitting to a tapered shaft

Roller-guided brass cage evenly spaces rollers for reduced friction, vibration, and noise

Open design, circumferential groove and three lubriexcavatorion holes in the outer ring allow for lubriexcavatorion in place
