Import Cylindrical Roller Bearing — Buy in Bulk from Supplier in China

Cylindrical roller bearings from Tjzrr Bearing Machine Development Co., Ltd are engineered for heavy radial loads, with most models in the N, NU, and NJ series designed for high-speed applications in machinery and industrial equipment. The bearings use chrome and bearing steel as standard materials, delivering durability under continuous stress and high-temperature environments typical in manufacturing and automotive sectors.

The N-type design supports radial loads only, while NU and NJ variants accommodate axial displacement in one direction, making them suitable for gearboxes, electric motors, and conveyor systems. Standard industry tolerances for cylindrical roller bearings include P0, P6, and P5 grades, with inner and outer ring concentricity held within strict ISO 492 limits. Typical cage materials are pressed steel or polyamide, with the latter offering lower friction at higher speeds.

These bearings are widely adopted in sectors such as mining, energy, and material handling, where precision and load capacity are critical. Buyers typically source them in bulk for OEM applications, with packaging and handling tailored to prevent contamination and damage during transit. Confirm compatibility with your application by verifying the bearing’s dynamic and static load ratings, as these vary by model and series.

Tjzrr Bearing Machine Development Co., Ltd is based in Tianjin, China, at No.2 Changleli, Chongqing Road, Heping District. The company’s profile indicates it operates as an imported-tier supplier, specialising in bearings and related components for industrial applications. Its harbor trust tier suggests it meets baseline verification standards for international trade.

The supplier’s current response rate is listed as 0.00, with no recorded average response time. This indicates buyers should expect delays in initial inquiries and may need to follow up directly via alternative contact methods. The company does not provide additional details on production capacity, certifications, or client history in its profile, so these should be clarified during direct discussions.
