SFRW3zz Miniature Flanged Ball Bearings with Extended Inner Ring have a lip extension on the outer ring. SFRW3zz bore dia is 0.1875″. Its out dia is 0.5″. SFRW3zz ball material is 440C Stainless Steel. Its seal type is Shielded. The SFRW3zz Miniature Flanged Ball Bearings with Extended Inner Ring can bear heavy radial loads and moderate thrust loads in both directions.
Typical applications include:
Miniature flange bearings are commonly used in industries such as food processing machinery, conveyors, material handling, belt drives in HVAC, textile machinery, baggage systems, medical processing, scanner motors, stepper motors, rotary encoders, card readers, etc.
General Selection Factors Several factors must be considered for choosing flanged ball bearings. These factors include the ring material, design, shields and seals, cage, Annual Bearing Engineering Committee (ABEC) grade, Seals and shields are used in miniature bearings (specifically ball bearings) to retain lubricants and prevent particulate contamination from reaching critical surfaces. Seals are used where minimal light contact is offered. Seals for miniature bearings provide deterrence to particulate contamination, but increase torque and limit operating speeds. Shields are used in most applications.
