Single Row Tapered Roller Bearings feature a classic design with tapered rollers and raceways, enabling them to accommodate heavy radial loads and combined loads with a single-direction axial component. With an optimized contact angle and high rigidity, these bearings provide excellent load-carrying capacity, stable operation, and reliable performance under high-speed or heavy-duty conditions. Their low friction and reduced heat generation help improve overall equipment efficiency.
Backed by over 20 years of bearing manufacturing experience, JRZC utilizes premium bearing steel, advanced heat treatment processes, and high-precision grinding equipment to ensure consistent dimensional accuracy and stable quality for every product. We also offer OEM/ODM customization services, including options for different structures, cage types, clearance classes, and surface treatments according to customer requirements. Supported by a strict quality control system and global supply capability, JRZC delivers high-performance Single Row Tapered Roller Bearings with competitive pricing and reliable lead times.

FAQ
Q1: What loads can Single Row Tapered Roller Bearings handle?
A: They can support heavy radial loads and combined loads with a single-direction axial component. For axial loads in both directions, bearings are typically used in matched pairs.
Q2: Can these bearings operate at high speeds? A: Yes. With proper lubrication and correct installation, Single Row Tapered Roller Bearings can perform reliably at relatively high speeds while maintaining low friction and stable temperature rise.
Q3: Do you offer customized Single Row Tapered Roller Bearings? A: Yes. JRZC provides OEM/ODM services, including customized dimensions, cage materials, internal clearance, accuracy grades, and special surface treatments.
Q4: What materials are used for your bearings? A: We use high-quality bearing steel and can also supply special materials upon request for specific operating environments.
