FAQ

Q Which Chinese manufacturers can replace ZIMMER and NBK full-series clamping elements?

A
LMT specializes in linear guide and linear shaft clamping elements. Our lineup includes manual, pneumatic, hydraulic and electric clamping elements, and we provide equivalent solutions for most mainstream ZIMMER / NBK series for your application validation.
Q Can LMT clamps replace Zimmer clamping elements? Are the mounting dimensions identical?

A LMT clamping elements can serve as replacements for Zimmer products, though the mounting dimensions are not 100% identical across all models. Some models share exactly the same mounting dimensions as Zimmer, while others have slight dimensional differences. If our standard version does not meet your requirement, we can customize clamping elements strictly to Zimmer’s dimensions. The customized units are priced the same as our standard ones, only with a longer lead time of about 7–15 days.
Q What types of clamping elements does LMT manufacture?

A LMT manufactures manual, pneumatic, electric and hydraulic linear clamping elements. We supply clamping elements for linear guide rails and linear shafts.
Q What are the common materials of self-reversing screw and nut block?

A
（1）Common materials for self-reversing screw: C45,SS303,SS304,440C,SS316,SS316L,40Cr,titanium alloy,2507 duplex stainless steel,GCr15,POM,nylon,38CrMoAl.

（2）Common materials for matching nut block: Brass,bronze,aluminum,C45,SS303,SS304,440C,SS316,SS316L,POM,PEEK,nylon.
Q What are the common applications of self-reversing screws?

A
Self-reversing screws are widely used in various industrial and mechanical scenarios,including:

1.Tethered drones

2. Ship deck equipment

3. Pipeline robots

4. Winding machines (including carbon fiber winding machines and strapping band winding machines)

5. Hose reelers / hose retractors

6. Agricultural sprayers (hose retraction systems for sprayers)

7. Textile machinery

8. Large-scale oilfield equipment
Q Why are same materials not recommended for designing self-reversing screw and nut?

A
When self reversing screw and nut adopt the same metal material, they are prone to galling, adhesion and seizure under friction and pressure operation. Identical material crystal structures easily bond with each other, resulting in thread locking, abnormal wear and short service life. Different material matching can effectively avoid bite failure, reduce friction and ensure stable long-running of reciprocating motion.
Q How does the efficiency of plastic nuts compare to copper alloy nuts?

A Plastic nuts generally have a 10% higher transmission efficiency than copper alloy nuts.
Q What is the typical transmission efficiency of a trapezoidal lead screw?

A The transmission efficiency of a trapezoidal lead screw is generally between 20% and 40%.
