product presentation
Stainless steel rod end spherical plain bearings are made of 304 or 316 stainless steel and feature a high-precision spherical sliding design, making them suitable for highly corrosive and high-load environments. The sliding contact surfaces of the product may be made of brass or polytetrafluoroethylene (PTFE) composite materials to reduce friction. It can adapt to the force and motion requirements in different directions. Meanwhile, by taking advantage of the characteristics of stainless steel, it can maintain good performance even in harsh environments.
product highlights
Superior Corrosion Resistance
304 Stainless Steel: Resistant to weak acids, alkalis, and salt solutions, ideal for food processing and medical equipment applications.
316 Stainless Steel: With higher molybdenum content, it offers enhanced resistance to chloride corrosion, suitable for marine and chemical processing environments.
**Chrome-zinc plated surface passes the 96-hour neutral salt spray test without rust formation.
01
High Precision & Low Friction
Spherical sliding contact surface precision reaches up to ±0.002mm, with an angular deviation range of 3° to 15°, allowing for installation error compensation.
Self-lubricating composite material reduces the friction coefficient to < 0.03, significantly lowering energy consumption.
02
High Load Capacity
Maximum static radial load reaches 5000N (Model HF12), with dynamic service life meeting the JB/T 8565 standard.
Capable of withstanding impact loads, suitable for hydraulic cylinders in construction machinery.
03
Maintenance-Free Design
Built-in PTFE or bronze liner eliminates the need for regular lubrication.
Sealed structure prevents dust ingress, extending service life.
04
Application Scenarios
Mechanical Lathe Equipment
