Insert Bearings
Turner insert bearings are replaceable components designed for use in our mounted ball bearing units, allowing worn bearings to be replaced without changing the entire housing assembly. Each series is engineered for a unique combination of load requirements and operating conditions, with different locking methods used to secure the inner ring to the shaft.
UC200 Series
UC200 inserts are general-duty ball bearing inserts with set screw locking and a single extended inner ring. They’re well-suited for light conveyors, fans, agricultural equipment, packaging machinery, and general industrial systems where rotation direction may vary and installation simplicity is a priority. In applications with high vibration or torque, eccentric or concentric locking styles may provide additional resistance to loosening.
Annealed set-screw ports and 120° screw spacing help maintain inner-ring roundness, reduce cracking risk, and support consistent shaft retention.
A single extended inner ring increases shaft contact area to help reduce inner-ring cocking.
A spherical outer diameter allows external self-alignment within compatible housings.
A precision-machined relubrication groove aligns with the housing zerk for consistent lubricant distribution and increased bearing life.
The Turner Advantage
SAE 52100 steel inner and outer rings provide consistent hardness and fatigue resistance that increases service life.
Optional L3 triple-lip seals increase sealing contact for better protection in severe contamination conditions.
Steel retainers improve durability under heat, shock, and variable loading compared to polymer cages.
Available with Lubrilife permanent lubrication for maximum contamination protection without routine maintenance.
Standard contact seals retain grease and block common industrial contaminants.
