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.
UE200 Series
UE inserts are general-duty ball bearing inserts that use Turner’s Tru-Loc concentric locking system to apply uniform 360° clamping around the shaft. Dual extended inner rings provide added shaft support, making UE inserts well-suited for reversing conveyors, fans, blowers, and other higher-speed equipment where vibration control and concentric rotation are important. Because the clamping force is distributed evenly rather than mechanically biting into the shaft, this design is not intended for heavy thrust or vertical shaft loading.
Turner’s Tru-Loc concentric locking collar applies uniform radial clamping force to maintain shaft concentricity and deliver smooth torque transmission while minimizing inner-ring distortion and shaft scoring.
Dual extended inner rings increase shaft contact area and help reduce inner-ring cocking.
A spherical outer diameter allows external self-alignment within compatible housings.
A precision-machined relubrication ring aligns with the housing grease fitting to direct grease into the ball path for consistent lubrication.
A black oxide coating provides light corrosion resistance and oil retention without affecting dimensional tolerances.
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.
