SW UC 202 Insert Bearing | 15mm Bore, Set Screw Lock | High-Performance Spherical Ball Bearing Unit
The SW UC 202 is a precision-engineered metric insert bearing designed for moderate to heavy industrial loads where alignment flexibility is critical. Featuring a 15mm straight bore and a spherical outer diameter (OD), this unit is specifically designed to fit into matching plummer block or flanged bearing housings (P, F, FL series) allowing for initial misalignment compensation. The unit incorporates a wide inner ring structure (UC type) which provides enhanced shaft support, resulting in reduced vibration and increased rigidity. SW utilizes high-quality 52100 bearing steel and effective contact seals (R3 or equivalent) combined with a robust labyrinth seal, ensuring superior contaminant exclusion and reliable retention of premium lithium soap grease, extending operational life in dusty or wash-down environments.
Optimized for ease of installation and maintenance, the UC 202 utilizes two integrated set screws (typically M6) spaced at 120 degrees on the extended inner ring. This reliable locking method ensures a secure, positive grip onto the shaft, minimizing slippage and fretting corrosion, even under reversing loads. Ideal applications include light-duty conveyor systems, HVAC blowers, agricultural equipment, textile machinery, and packaging lines that require periodic self-correction and dependable, sealed lubrication. Selecting the SW UC 202 guarantees exceptional durability and reduced downtime, upholding stringent ISO quality standards required by professional industrial environments.
