Plain Spherical Bearing With Graphite – VIIPLUS

We have the best instructors

It can rotate and swing at any angle when moving. The VIIPLUS graphite spherical bearing can greatly save time and reduce the difficulty of assembly.

Characteristics Of Graphite Spherical Bearing

  • Maintenance-free features quite long service life.
  • Conforms to ISO Standard E type bearings. High precision.
  • The inner surface of the inner ring is subject to sliding. The outer surface of the outer ring bear self-aligning.
  • Suitable for higher load than other self-lubricating Spherical Plain Bearings.
  • Applicable to large oscillating angles in circumferential oscillating motion.
  • Customized design can be made on your requirement.

The benefits of oilless bronze bearings

Maintenance-free Radial graphite spherical bearing | Applications

Oilless graphite spherical bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery, and other industries. Spherical plain bearings, the basic type is composed of inner and outer rings with the spherical sliding spherical contact surface. According to its structure and type, it can bear radial load, axial load, or radial, axial simultaneous action of the combined load.

Steel Outer W/ Copper Alloy Inner – Metric Series

Most plain spherical bearings have adopted special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, padding, spraying, etc., so they have greater load capacity and impact resistance, and have corrosion resistance, Wear-resistant, self-aligning, well lubricated or self-lubricating without contamination by lubricating dirt

Steel spherical bearing

When the sliding surface material of self-lubricating spherical plain bearings is steel, the permissible operating temperature depends on the permissible operating temperature of the lubricant.
