wall bearing with equal cross-section is a specially designed thin-walled rolling bearing. Its core feature is that the wall thickness is uniform and significantly lower than that of standard bearings, while maintaining the consistency of cross-section size, which is suitable for fields that require extremely high space, weight and accuracy.
structural characteristics/property Thin-walled design: the wall thickness is usually 1-5mm (about 5-15mm for standard bearings), and the ratio of section height to radial size is optimized to reduce material redundancy.
Equal cross-section structure: the cross-section dimensions of the inner and outer rings and the rolling element assembly are consistent, so as to ensure the uniform distribution of load and avoid local stress concentration.
Lightweight materials: High-strength stainless steel (such as 440C, 304) or aluminum alloy, combined with precision cold forging process.
Compact configuration: the rollers are arranged in a close-packed way, usually in a full-loaded roller or cross-roller structure to enhance rigidity.
Performance advantage High space utilization: 30%-50% less installation space than standard bearings of the same size, suitable for narrow cavities. Lightweight: the weight is reduced by 40%-60%, which is beneficial to high-speed motion systems (such as robot joints).
