Tapered Bore Insert Ball Bearing

ZWZ UK series insert ball bearings are engineered for heavy-duty industrial applications where secure shaft fixation and precise concentricity are critical. Featuring a 1:12 tapered inner bore, they work with adapter sleeves to eliminate shaft play and ensure rigid mounting. This design provides higher load capacity and better fatigue resistance than standard straight-bore insert bearings.

Key Features

● Tapered bore (1:12): Works with adapter sleeves for zero-play shaft mounting

● High-precision raceways: Enhanced load distribution and reduced friction

● Triple protection seals: Labyrinth + contact seals for harsh environment resistance

● Heavy-duty construction: Hardened steel components for extended service life

● Self-aligning design: Compensates for significant shaft misalignment

Tapered Bore Insert Ball Bearing UK Series3

Core Advantages

● Superior concentricity: Eliminates radial runout, ideal for high-torque applications

● Higher load capacity: Up to 30% higher radial load rating than UC series

● Shock resistance: Withstands heavy shock loads and vibration

● Easy installation/removal: Adapter sleeve simplifies mounting and dismounting

● Long service life: Premium materials and precision manufacturing reduce maintenance

FAQ

Q: When should I choose UK series over UC series?

A: Choose UK series for heavy-duty applications with high torque, shock loads, or where precise shaft concentricity is required.

Q: Do I need special tools to install UK series bearings?

A: Basic installation tools are sufficient, but a nut and hook spanner are recommended for proper adapter sleeve tightening.

Q: Can UK bearings be used with standard shafts?

A: Yes, they are designed for standard smooth shafts using the included adapter sleeve.
