Temperature, which indicates the maximum operating temperature of the material.
Speed indicates the ability of the material to adapt to the operating speed. 🌑 The more, the better
Load, which indicates the ability of the material to fit the weight. 🌑 The more, the better the load-bearing
Wear resistance indicates the overall performance of the material in terms of wear and friction. 🌑 The more, the better the durability.
UV resistance, indicating the material's resistance to UV rays. 🌑 The more, the better the resistance.
Dimensional stability - moisture absorption means that the size change of the material when absorbing water and moisture, 🌑 the more the size change will be.
Dimensional stability - temperature means that the size of 🌑 the material is affected by the temperature rise or fall, the more the size change is smaller.
The adaptability to aluminum means that the more the material rubs against the aluminum alloy material, 🌑 the better the performance.
Adaptability to iron means the performance of the material when it rubs against the iron material, 🌑 and the more, the better the performance.

Self-lubricating bushing – DBH07090401-904B1

Dimensions:

 

Pressing instructions

The inner diameter of the bushing is the only one with marked tolerances, and the inner diameter size is measured after the bushing is installed in the hole (Hole, Housing).
The size of the inner hole (Housing) of the detection fixture is Φ8.80, the tolerance is +0.000 ~ +0.005 mm, and then the bushing DBH07090401-904B1 is pressed into it, then the inner diameter size of the bushing will be within the tolerance.
 

The size and tolerance of the matching parts

The tolerances we provide are an ideal and recommended value that will vary depending on usage and individual user feelings and preferences. In addition, the tolerances we provide are tight outer diameter and loose inner diameter.

---

shaft
The shaft size is Ø6.80mm. Tolerances, recommended from +0.00 to -0.04 mm.

---

Hole, Housing
The size of the hole is Ø8.80mm. Tolerances, recommended from +0.00 to +0.02 mm.

Axis requirements

The friction coefficient, hardness and roughness of the shaft affect the wear resistance and vibration between the shaft lining and the metal, and the following is the recommended value (reference).

• Hardness HRC 40
• The roughness is less than RA 0.8 um
