Steel Roller
From IQC,IPQC to OQC is what we consider.Jimway offers an extensive testing equipment, such as dustproof,waterproof,dynamic balance,drag,and T.I.R to meet the needs of maximum service life,quiet operation, and the best performance.As the manufacturer,we provide as much idlers description as we can, from JIS,CEMA , DIN and ISO standard to custom-designed idlers.

| Pipe OD. | Ø89.1~Ø159mm |
| Shaft OD | Ø20~Ø35 |
| Size | Be customized |
Shaft
- CNC machined and diameter tolerance:JIS h7
Bearing
- The lubrication of 2RS deep groove ball bearings with NTN,SKF,FAG ,and C&U brand for reducing friction between parts during relative movement to ensure the bearing effective operation even temperature rise
Bearing housings
- CNC machined and bearing housing seat tolerance:JIS N7
Labyrinth seals
- Less deformation due to good compressibility and resilience
- Grease-filled labyrinth seal
- Dust,water ,and pollution sources prevention
- Effective operation in a wide temperature range
Grease
- Non-rubbing,protecting for bearing,and saving power due to good quality greases for two particular temperature range (-20°C~+65°C, -40°C~+65°C)
Powder coating
- One of the most environment-friendly coating ststems to coat in the range of 50~300um per one cycle.Powder coating with good impact resistance not easily rubbed off when handling the roller.
- Removing rust and degreasing parts before powder coating for effective operation and the belt service life extension.
