Description

Design Principles Four-Point Contact: Each ball contacts the raceway at four points, distributing loads evenly. Modular Structure: Split rings bolted together for easy assembly and maintenance. Gear Flexibility: Choose internal/external gears or gearless designs based on drive mechanisms. Performance Highlights High Precision: Runout tolerance ≤0.008 mm for critical applications. Long Service Life: Advanced heat treatment extends fatigue resistance by 25%. Space Efficiency: Compact design ideal for equipment with limited installation space.

Features

Multi-Load Capacity

Handles axial, radial, and moment loads in a single bearing.

Customizable

Options for gears, seals, and non-standard dimensions.

Low Maintenance

Sealed-for-life designs reduce lubrication frequency.

High-Speed Adaptability

Disc cage configurations support higher rotational speeds.

Working Principle

Load Distribution Axial & Radial Loads: Transferred through four-point contact balls, balancing stress across raceways. Moment Loads: Resisted by diagonal ball contact, minimizing localized deformation. Lubrication & Sealing Grease Lubrication: Standard for general applications (replenishment every 500–800 hours). Oil Lubrication: Recommended for high-speed or high-temperature environments. Sealing: Multi-layer seals prevent contamination from dust, water, and debris.

FAQ

What distinguishes four-point contact bearings from crossed roller bearings?

Four-point contact bearings use balls for combined loads in a compact design, while crossed roller bearings use cylindrical rollers for higher rigidity.

How to choose between internal and external gears?

Internal gears suit central pinion drives; external gears fit peripheral drive systems.

Can NEWBEE bearings handle high-speed rotation?

Yes, with disc cage designs, speeds up to 50 rpm are achievable.

What causes noise in four-point contact bearings?

Common causes include misalignment, insufficient lubrication, or wear.
