Get Fastest Delivery / Get Best In Market Rates / 43+ Years Of Experince

Balaji Bearings, a prominent manufacturer of precision bearings for combined loads, has offered speciality bearing pivots vital in discrete high-bench machinery. We are a reliable distributor with clients across Sri Lanka, South Africa, the UAE, Nigeria, Egypt, Indonesia, Thailand, and Kuwait. Our exact bearings are designed to support heavy radial and axial forces simultaneously with excellent rotational precision and rigidity.

Essential Uses of High-Precision Bearings for Combined Loads

• CNC Machine Tool Spindles: The spindles are the heart of any high-speed spindle, as the spindle is required to offer extreme axial and radial stiffness needed to hold the tool in position and permit cutting accuracies down to the micron scale.
• Precision Rotary Tables: These bearings are used in multi-axis machining or in inspection machines and are designed to carry the weight of the workpiece (axial load) and the cutting forces (combined loads), but have to offer the highest indexing accuracy.
• Grinding and Lapping Machines: During finish-machining operations, the bearings must sustain the combined forces with the minimum run-out essential to recover a high-quality surface finish on parts.
• Turbo Machinery: These bearings assist the rotor of high-speed, compact turbo and compressors in withstanding both the weight (radial load) and the huge forces caused by the compressor blades at a higher RPM.

Characteristics of High-Precision Bearings for Combined Loads

• High Preload Capability: These bearings are designed with preloading (typically mounted and designed to be used in pairs or more) to remove internal clearance. This greatly improves the rigidity of the system and accuracy of rotation.
• Ultra-High Speed Capacity: Special cages, special internal geometry and typically high-quality ceramic balls enable them to exhibit a minimum of friction and heat generation over a wide range of rotational speeds at which they can be confidently operated.
• Extraordinary Rotational Accuracy (Low Runout): They are produced to ABEC 7/9 (P4/P2) levels of radial-axial runout, which are exceptionally low to provide extraordinary machining and positioning accuracy.
• High Stiffness-to-Weight Ratio: The designs (commonly Angular Contact Ball or Tapered Roller) are designed to be as rigid as possible to deflection due to the presence of combined forces in as small a physical volume as possible.
