# 780708K: 40 × 114 × 34 mm Field Notes
The envelope to write on the ticket is 40 × 114 × 34 mm. That geometry belongs to 780708K, a forklift chain / sprocket ball bearing with H groove. Measure the removed part or the housing before you trust a faded stamp.
Contents
Typical duty includes forklift mast chains and H-groove sprocket positions. Material on this listing is GCr15. If your equipment sits outside that range, say so on the request rather than forcing a familiar part number.
Do not substitute a plain 40 mm ball bearing without the H groove, or a 780708KS variant without a drawing. The groove and the 40×114×34 mm envelope define this part. A standard deep groove of similar bore will not run in the chain track.
Review 780708K on the TFL Bearing Made-in-China listing. Shandong TFL Bearing Co., Ltd can confirm stock, packing, and any OEM marking once the drawing or sample is attached.
