High Light Metric radial spherical plain bearing 75x120x64mmSteel-on-steel bushing for heavy dutyGrease fitted spherical bearing swing joints
1. Product Overview

SB75A is heavy-duty radial spherical plain bearing of SB-A series, constructed with inner ring and outer ring adopting steel-on-steel friction pair, equipped with built-in grease fitting for regular supplementary lubriion. Its spherical contact surface allows maximum 5° self-aligning tilt angle, capable of enduring large radial load plus bidirectional axial load, perfectly matching swing, oscillating and misaligned transmission joints of heavy machinery.

Formal quotation will be sent within 24 hours upon your inquiry.

2. Technical Specifiions

3. Core Advantages
  1. Steel-on-steel contact structure delivers ultra-high static & dynamic load capacity for heavy-load swing working conditions
  2. Spherical sliding surface realizes 5° self-alignment, compensates installation deviation and shaft deflection automatically
  3. Reserved grease injection hole facilitates regular lubriion to reduce friction and extend service life
  4. Separable inner and outer ring allows independent interference fit on shaft and housing, convenient disassembly and maintenance
  5. Compact integral structure saves installation space compared with rod end bearing assemblies
  6. Standard metric ISO dimension, fully interchangeable with same-spec spherical plain bearings
  7. Customizable options: double side rubber seals, anti-corrosion surface coating, OEM laser marking, high-temperature lubricant
    Effectively reduce swing friction noise, prevent metal seizure and lower long-term equipment maintenance cost.
