BS Series High-precision Ball Screw Bearings with Double Seals

The inner and outer rings of the BS series high-precision ball screw bearings with double seals are made of high-purity bearing steel with strict control over oxide impurities that are harmful to rolling fatigue life. Through structural designs such as a contact angle of 60º and a large number of steel balls, the BS series sealed ball screw bearings possess greater axial stiffness. Compared with tapered roller bearings and cylindrical roller bearings, they have a smaller starting torque, achieving low driving force and high-precision operation. When used in pairs, they can withstand axial loads, radial loads, or combined loads.

Dentail

High stiffness: Thanks to the special contact angle and multi-steel ball design, it provides solid axial support for precision machinery and maintains structural stability.
Low starting torque: It starts easily and consumes low energy, especially suitable for equipment that is sensitive to power and has frequent start-stop operations.
High precision: The stable structure and high-quality materials ensure extremely small rotational errors, meeting the requirements of precision machining and measurement.
Good sealing: The double seal resists external pollution, adapts to harsh working conditions such as dusty and humid environments, and reduces maintenance frequency.

Application

The bearings can be used in the following industries

Precision Machine Tools: Such as CNC machining centers and grinding machines, ensuring the precise movement of cutting tools to machine complex precision parts.
Automation Equipment: Robot joints in industrial robots and linear modules in automated production lines, facilitating precise motion execution.
Precision Measurement Instruments: Coordinate measuring machines, etc., guaranteeing the accurate displacement of measuring heads and reliable data.
Medical Devices: Fine-tuning of surgical microscopes and lifting of dental treatment chairs, providing stable and high-precision transmission.
Electronic Manufacturing Equipment: Chip lithography machines and pick-and-place machines, meeting micro-precision operations and ensuring the quality of electronic products.
