24124Spherical Roller Bearings

24124 Spherical Roller Bearing | 24124CA / 24124CC / 24124K Cage And Application

The 24124 is a widely used wide-width double-row spherical roller bearing with standard dimensions of 120×200×80mm. Featuring excellent self-aligning performance, ultra-strong radial and axial load capacity and low-friction stable rotation, this bearing can effectively compensate shaft misalignment and absorb continuous mechanical vibration. Designed for long-term medium-speed heavy-load and intermittent shock-load operation, it is a core transmission component for medium and large heavy industrial machinery. The 24124 series includes three classic models: 24124CA, 24124CC and 24124K, with differentiated cage and bore structures to meet diversified industrial working conditions and maintenance needs.

24124CA Bearing (Solid Brass Cage)

24124CA adopts a one-piece precision machined solid brass cage with symmetrical roller layout and ribless inner ring design. The high-rigidity integral brass cage delivers outstanding high-temperature resistance, impact toughness and anti-fatigue performance. It effectively reduces internal friction, heat accumulation and operating noise during long-duration continuous operation. Resistant to structural deformation under shock loads and harsh high-temperature environments, this model maintains precise roller operation and ultra-high stability. With superior durability and low failure rate, 24124CA is the preferred solution for critical industrial equipment operating in harsh working conditions.

24124CC Bearing (Stamped Steel Cage)

24124CC 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 greatly improves overall load-bearing efficiency. Featuring low friction coefficient, excellent wear resistance and stable medium-speed performance, this model adopts standardized manufacturing process with high versatility and excellent cost performance. It runs steadily under cyclic heavy-load conditions and resists daily vibration and abrasion, serving as the most cost-effective universal model for conventional heavy-duty industrial machinery.

24124K Bearing (Tapered Bore)

24124K features a 1:12 tapered bore design with adjustable internal clearance. Compatible with adapter sleeves and withdrawal sleeves, it supports fast installation, disassembly and accurate clearance calibration. The tapered bore structure effectively corrects shaft assembly errors and mechanical deflection, significantly improving the stability of heavy-load transmission systems. Inheriting all self-aligning and super-heavy load advantages of standard spherical roller bearings, it enables flexible assembly and simple routine maintenance for equipment requiring regular debugging and overhaul.

Industrial Applications

24124 series bearings are widely applied in heavy industrial fields. 24124CA is suitable for high-temperature and high-impact equipment including metallurgical rolling mills, heavy-duty reducers and large mining machinery. 24124CC fits general heavy machinery such as large construction equipment, vibrating screens, chemical and paper-making machines. 24124K is commonly used in industrial fans, large conveyor systems and transmission equipment needing adjustable clearance and convenient daily maintenance.

Product Summary: 24124CA focuses on high reliability and harsh environment adaptability, 24124CC provides stable and cost-effective universal performance, and 24124K offers flexible adjustable assembly solutions, fully covering medium-speed and heavy-load industrial operation scenarios.
