Tapered roller bearing 30210 is a separable single-row bearing designed to withstand combined radial and axial loads, widely used in industrial machinery, agricultural equipment, and the new energy field.
Bore diameter: 50mm; outer diameter: 90mm; total width: 21.75mm; inner ring width: 20mm; outer ring width: 17mm; contact angle: 15.642°. Weight typically ranges from 0.53kg to 0.64kg.
Features separable design allowing independent installation of inner ring assembly and outer ring for easier maintenance and clearance adjustment. The line contact design between rollers and raceways enables high load capacity with low friction coefficient and extended service life.
Commonly used in reducers, winches, plastic granulators, and tool magazines of machining centers. Provides high load-carrying capacity and impact resistance for heavy-load requirements.
Suitable for backhoe loaders, bottom presses, and various agricultural machinery, demonstrating excellent economy and reliability.
Applied in new energy vehicle transmissions by manufacturers such as Jiangsu Luyue, meeting high-speed and high-precision transmission requirements.
Regularly monitor temperature, vibration, and noise. If temperature exceeds 70°C, shorten lubrication cycle. Use special tools for disassembly to avoid damaging raceway surfaces.
Complies with DIN ISO 355 and DIN 720 standards. Some manufacturers have obtained CE certification, ensuring product quality and interchangeability.
Tapered roller bearing 30210, with its high load-carrying capacity, low friction, and separable design, has become a core component in industrial transmission. When selecting, users should comprehensively consider working conditions (load ratio, speed, ambient temperature) and maintenance costs for optimal performance and reliability.
