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.
UK200 Series
UK inserts are general-duty ball bearing inserts with a tapered bore that mount using an adapter sleeve. The sleeve expands against the shaft and draws the inner ring onto the tapered seat, creating a secure interference fit that transmits torque reliably under vibration or reverse rotation. This design is well-suited for conveyors, heavy-duty fans, HVAC applications, and other equipment where shaft tolerances vary and consistent rotational accuracy is important.
Tapered adapter sleeves provide secure shaft retention and allow controlled removal without shaft damage.
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.
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.
