These sliding bearings use an Oiles bearing as a sliding material.
BP・A A high-strength brass BP bearing Fixed & movable
The Oiles BP・A is a sliding bearing that uses an oil-less BP, which has excellent corrosion resistance, load-carrying capacity, wear resistance, and a low coefficient of friction, as the sliding material.
Features
- It maintains consistent performance over a long period of time for features required of bearings, such as support of a load and absorption of girder expansion/contraction and rotation.
- An Oiles BP is used as the sliding material, providing an extremely low coefficient of friction and excellent load resistance.
- Oiles BPs have excellent corrosion resistance, weather resistance, and durability, and they perform well under harsh conditions.
BP・B A sealed rubber BP bearing Fixed & movable
The Oiles BP・B is a sliding bearing that uses an Oiles Glitron plate, which has excellent corrosion resistance, load-carrying capacity, abrasion resistance, and a low coefficient of friction, as the sliding material. Chloroprene rubber is sealed inside the lower shoe by an intermediate plate.
Features
- It maintains consistent performance over a long period of time for features required of bearings, such as support of a load and absorption of girder expansion/contraction and rotation.
- The Oiles Glitron Plate has an extremely low coefficient of friction and excellent friction and load-carrying capacity.
- Chloroprene rubber has excellent resistance to weather, ozone, oil, and heat, and it performs well under harsh conditions.
Basic characteristics
Oiles BPs
Oiles BPs are based on grade four high-strength brass (JIS H 5120) castings made with advanced casting technology and embedded with a special solid lubricant. The lubricant maintains consistent characteristics by evenly forming a lubricating film with respect to sliding in any direction.

|---|---|---|
| Tensile strength | Elongation | Brinell hardness |
| 755 N/mm2 or more | 12% or more | 200 or more |
Oiles Glitron plate (Sliding Plate)
Oiles Glitron plates are based on polytetrafluoroethylene (PTFE) with special fillers and have an extremely low coefficient of friction, excellent corrosion resistance, load-carrying capacity, and abrasion resistance.

| Tensile strength | 1,400 N/mm2 or more |
| Elongation | 90% or more |
| Chemical resistance | It is virtually impervious to acids and alkalis. |
Chloroprene rubber (rubber plate)
Chloroprene rubber has excellent durability, weather resistance, ozone resistance, heat resistance, and oil resistance.
| Characteristics of chloroprene rubber (Test method: JIS K 6301) | |
|---|---|
| Static shear modulus | 80±10 N/mm2 |
| Elongation | 400% or more |
| Change in hardness (JISA) | 0- +15 (100°C x 70 h) |
| Rate of change in elongation | -50% or more (100°C x 70 h) |
| Compression set | 35% or less (100°C x 22 h) |
