Punched outer ring needle roller bearing (full loaded needle roller series) is a bearing unit composed of thin-walled outer ring and needle roller. Its main characteristics are that the grinding shaft is used as the raceway, the radial space structure is particularly small, the cost is low, the bearing capacity is high, and the installation is convenient. This series of bearings are widely used for supporting running components such as automobiles and motorcycles.
1. Structural form
This type of bearing is of perforated type and sealed type, and the applicable shaft diameter is generally φ 6～ φ 45mm range.
2. Product precision
The difference between needle diameters is 3 μ m. The accuracy grade is G3 (international GB/T309), which can also be determined according to user requirements.
The tolerance of outer ring width C is 0 to -0.3mm
Due to the deformation of thin-walled outer ring after heat treatment, the dimensional accuracy of outer ring D and inscribed circle diameter cannot be inspected under the free state before installation, and shall be inspected as follows:
1) The diameter tolerance of the inscribed circle Fws is checked by pressing the bearing into a hardened steel ring gauge with a specific inner diameter and then using a plug gauge with a "go" and a "no go" end.
2) The test of outer ring D tolerance is best determined by testing the bearing's pressing force when pressing the ring gauge in 1) above.
3. Materials
The needle roller is made of GCr15 bearing steel.
The stamping thin-walled outer ring is made of high-quality low-carbon steel.
4. Precautions for use and installation:
The thin-walled outer ring shall be equipped with a rigid seat hole to give full play to its bearing capacity.
The bearing shall be pressed into the bearing seat hole with an assembly mandrel. The shoulder of the assembly mandrel shall contact the bearing marking surface, and the non marking surface cannot bear the assembly force directly.
The bearings we produce are mainly used for: automobile parts, motorcycle parts, textile machinery, packaging machinery, food machinery, other machinery, etc
