This Browning VB-200 series 52100 chrome steel ball bearing insert with contact and flinger seals is designed to fit into mounted housing units and locks onto the shaft with a concentric (BOA) locking collar clamp and two cap screws (TORX) for 360-degree holding power. This lock type reduces vibration, does not mar the shaft, and is suitable for high-speed applications where the shaft rotates in a single or reversing direction. For increased shaft support and holding power, the bearing has an extended inner ring on one side and a zone-hardened inner race. A rivet on the outer ring prevents rotation of the ring in the housing, reducing heat buildup and prolonging the bearing life. The bearing is rated “normal-duty” for supporting moderate loads, and when combined with a matching Browning housing (sold separately), its convex sphered outer surface helps compensate for moderate initial misalignment errors. Buna-nitrile (Buna-n) single lip contact seals on both sides of the bearing help keep out contaminants, such as dirt and grime, and hold in lithium complex National Lubrication Grease Institute (NLGI) 2 grease applied at manufacture. For improved protection in harsh environments without increased friction, black oxide treated flingers on both sides of the inner ring deflect contaminants away from the seals. This single-row ball bearing insert, made of 52100 chrome steel for durability and resistance to deformity, supports radial and thrust loads. A nylon retainer evenly spaces the grade 10 balls on the raceways for reduced friction, vibration, and noise. Ball bearing inserts are used in various industrial applications including mining equipment, fans and blowers, conveyors, and agricultural equipment, among others.
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.
