- Produced in strict accordance with OEM drawing specifications, outline size and hole position fully consistent with original spare parts, direct replacement without trimming, save assembly adjustment time during overhaul.
- High-precision sheet processing, consistent thickness tolerance, excellent flatness, ensure uniform force after padding, avoid local stress concentration.
- Good compression resistance and stable shape retention, not easy to bend or thin under long-term assembly preload and cyclic vibration, keep gap parameters stable.
- Burr-free cutting edge, prevent scratch on mating metal surface during assembly, protect the precision surface of matching parts.
- Surface anti-rust oil treatment, effective against moisture and light corrosion during storage and assembly, convenient storage and onsite use.
- Flexible combination mode, multiple shims of different thickness can be matched freely, to meet precise clearance requirements of different assembly positions.

FAQ 

Q1: Where is this adjusting shim commonly installed?
A1：It is widely used in drive axle, hinge joint, gearbox and working device assembly clearance adjustment.

Q2: When do we need to replace adjusting shims?
A2: Excessive or too small assembly clearance, obvious axial play, abnormal noise during component operation, shim deformation, scratch, corrosion and thinning.

Q3: What will happen if improper thickness shim is used?
A3：Too thin will lead to large gap, component axial play, impact and abnormal noise. Too thick will cause excessive preload, increase friction heat and accelerate part wear.

Q4: What precautions should be noted during installation?
A4：Clean the mating surfaces thoroughly to remove metal debris and dirt; place the shim flat without warping; avoid debris sandwiched between fitting surfaces.

Q5: Can multiple shims be stacked for adjustment?
A5：Stacking is allowed for fine adjustment. But try to reduce the number of stacked pieces as much as possible to avoid cumulative error and loose vibration displacement.

Q6: What factors cause adjusting shim damage?
A6：Sand and metal chips clamped on mating surface, excessive assembly preload, repeated impact vibration, long-term corrosion thinning.

Q7: Can damaged shim be reused after polishing?
A7：Not recommended. Polishing will change the original thickness and flatness, affect assembly accuracy, replace new shim directly.

Q8: Can this shim be used in mine heavy-duty working conditions?
A8：Yes. High-strength steel material with stable thickness, suitable for clearance adjustment of loader key transmission parts under mine working environment.
