Compact Turntable Bearings
Introduction
The high precision crossed roller bearings range 88 has been designed to meet customers' specific expectations and requirements in terms of application. The high precision crossed roller bearings range 88 offers high precision in positioning, which provides significant advantages for robots, indexing tables, positioners, machine tools, turntables, tool changers, welding cells, and other applications. Its high stiffness, homogeneous rotation with low torque, and high geometric quality make it an ideal choice for a wide range of industrial applications.
The crossed roller design with preload and ground raceway ensures reliable performance over the lifetime of the machine.
Features of Turntable Bearings
1. High Load Capacity: Turntable bearings can support substantial radial, axial, and tilting moment loads.
2. Smooth Rotation: They are designed to allow smooth, continuous rotation even under heavy load.
3. Precision: Some bearings are designed with high precision for applications where accurate positioning is critical, like in machinery or robotics.
How to Select a Turntable Bearing
1. Load Requirements: Determine the type (axial, radial, moment) and magnitude of the load.
2. Precision: Higher precision bearings may be required for robotics or medical equipment.
3. Environmental Factors: Consider dust, moisture, and temperature, as these can impact bearing performance.
4. Mounting Design: Some applications may benefit from flange-mounted designs for ease of installation.
