2、All specification and types of timing belt can be produced;so do other specification and types
of timing belt not listed in this table
3、For particular specification belt,we can make according to the clients' supplying drawing or
sample after negotiation.
4、Timing belts' width can be adjusted as clients' request.
5、This company may otfer desigh for choosing timing belt specification & types or drip in to
provide technrvices as per customers' technical requirements.
