SD110AR0 Bearing Product Overview & Core Advantages
The SD110AR0 is a thin section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim Stainless Steel Bearings series, it features a single row design with a 30° contact angle, enabling it to support substantial combined loads—both radial and axial. Its stainless steel construction provides excellent corrosion resistance, making it suitable for harsh environments. With an ABEC-1 tolerance class and precise dimensional control, this bearing delivers reliable performance in high-precision applications where compactness and weight savings are critical.

SD110AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The bearing's slim cross-section (0.5" width) enables compact bearing arrangements while maintaining high load capacity, ideal for space-constrained applications.
High Load Capacity: The 30° contact angle and optimized raceway geometry provide excellent combined load capability, with a radial dynamic load rating of 3133 lbf and axial static load rating of 7960 lbf.
Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore and OD tolerance: -0.0014" to 0"), ensuring smooth operation and minimal runout in precision applications.
Corrosion Resistance: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering superior corrosion resistance and suitability for temperatures from -30°C to 110°C.
Moment Load Capacity: Features a substantial static load moment rating of 26220 lbf, providing stability in applications subject to overturning moments.
SD110AR0 Bearing Typical Application Areas
The SD110AR0 thin section angular contact bearing is ideally suited for:
- Robotics and automation systems - where compact size and precision motion control are essential
- Aerospace components - including gimbal systems and satellite mechanisms requiring corrosion resistance
- Medical equipment - particularly in imaging systems and surgical robots demanding high precision
- Semiconductor manufacturing equipment - where cleanroom compatibility and precision are critical
- Optical positioning systems - requiring minimal deflection and high angular accuracy
- Rotary tables and indexing heads - benefiting from the bearing's moment load capacity
