23940Spherical Roller Bearings

23940 Spherical Roller Bearing | 23940CA / 23940CC / 23940K Cage And Application

The 23940 is a large-size double-row spherical roller bearing with standard dimensions of 200×280×60mm. Featuring compact structure, excellent self-aligning performance and extreme radial load capacity, this bearing effectively compensates shaft misalignment, absorbs mechanical vibration and withstands long-term low-speed heavy-torque operation. As a key heavy-duty component for large industrial machinery, the 23940 series covers three mainstream models: 23940CA, 23940CC and 23940K. Different cage structures and bore designs meet differentiated working condition, cost and maintenance requirements for industrial applications.

23940CA Bearing (Solid Brass Cage)

23940CA adopts a one-piece precision machined solid brass cage with symmetrical roller layout and ribless inner ring structure. The high-rigidity brass cage delivers outstanding high-temperature resistance, anti-fatigue and impact-resistant performance, maintaining stable structural performance under continuous heavy-load operation. It reduces internal friction, heat accumulation and running noise while ensuring accurate roller operation. Resistant to deformation under shock loads and harsh high-temperature environments, this model features ultra-high reliability and extended service life, making it the preferred choice for critical large-scale industrial equipment with zero-failure operation requirements.

23940CC Bearing (Stamped Steel Cage)

23940CC is equipped with a two-piece stamped steel cage and floating guide structure. The lightweight steel structure optimizes internal bearing space, expands roller contact area and improves overall load-bearing efficiency. With low friction coefficient, excellent wear resistance and stable medium-speed operation, this model adopts standardized manufacturing process with high versatility and superior cost performance. It runs steadily under cyclic heavy-load conditions, effectively resisting daily mechanical vibration and abrasion, serving as the most cost-effective universal model for conventional heavy industrial machinery.

23940K Bearing (Tapered Bore)

23940K features a 1:12 tapered bore design with adjustable internal clearance. It can be perfectly matched with adapter sleeves and withdrawal sleeves to realize fast installation, disassembly and precise clearance calibration. The tapered bore structure effectively corrects shaft assembly errors and mechanical deflection, greatly improving the overall stability of heavy-load transmission systems. Inheriting all self-aligning and super-heavy load advantages of standard spherical roller bearings, it supports flexible assembly and simple routine maintenance, ideal for equipment requiring regular inspection and performance debugging.

Industrial Applications

23940 series bearings are widely used in large heavy-duty industrial fields. 23940CA is suitable for high-temperature and high-shock equipment including metallurgical machinery, heavy industrial reducers and large mining equipment. 23940CC applies to general heavy machinery such as large construction equipment, vibrating screens, chemical and paper-making production machines. 23940K is commonly installed on large industrial fans, heavy conveyor systems and transmission equipment needing adjustable clearance and convenient maintenance.

Product Summary: 23940CA focuses on high durability for harsh working environments, 23940CC provides stable cost-effective universal performance, and 23940K offers flexible adjustable assembly solutions, fully covering low and medium-speed heavy-load industrial operation scenarios.
