PB Series Radial Spherical Plain Bearings(PB5 PB6 PB8 PB10 PB12 PB14 PB16 PB18 PB20 PB22 PB25 PB28 PB30)
Spherical plain bearings are used for applications requiring rotation and oscillation. The rotation takes place on a sliding
surface so the limiting speed is slow.
We can supply high quality and almost all types of spherical plain bearing,
- Radial Spherical Plain Bearings
- Angular Contact Spherical Plain Bearings
- Thrust Spherical Plain Bearings
- Non-standard Spherical Plain Bearings
Applications:
Railway engineering
Railway station construction
Bridge building
Construction machinery
Hydraulic steel structures
Roof designs
Power generation
Oil field exploration
Mining and aggregate processing
Wind turbines
Gear drives
Rolling mills
Technical specification
GEZ…ES-2RS:As series GE…ES-2RS,but with inch dimensions.
Here is the comparison between each standard organization:
ABEC-1, ABEC-3, ABEC-5, ABEC-7, ABEC-9, the larger the number, the higher the precision grade.
| ANSI Standard* | DIN 620* | ISO 492* |
| ABEC 1 | P0 | Class Normal |
| ABEC 3 | P6 | Class 6 |
| ABEC 5 | P5 | Class 5 |
| ABEC 7 | P4 | Class 4 |
| ABEC 9 | P2 | Class 2 |
1) Sliding contact surfaces: Steel vs. bronze.
2) Materials: Outer race is made of carbon steel, inner race is made of high chrome bearing steel, medium race is bronze.
3) Heat treatment: Without heat treatment on outer race and bronze race. Inner race is quenched (hardened), and surface plated with chrome.
4) Features of structure: With oil groove or oil hole. Outer race formed by extrusion. With a bronze race between outer race and inner race.
5) Properties: Self-lubricated, low friction, good wearability, self-alignment.
