This is an anti-backlash nut that works with the 1/2" 10 TPI (Threads Per Inch) 5 start Lead Screw.

This is a 1/2" 5 start and 10 TPI ACME precision lead screw that translates to 2 turns per inch. Use this to serve as your main mechanics to move an axis of your CNC machine. Couple this with our anti-backlash nut with the same specifications. The quantity is priced per inch. Total length = quantity in inches.

This is a ball screw and ball nut just shy of 1 inch major diameter (24.86mm). The lead is 5 turns per inch approximately (24.91mm after 5 turns.). This ball screw will provide for a smooth, easy and precise movement to CNC routers and machines. The length of threaded length is 1900mm.

This is a nut that uses a spring to reduce/eliminate backlash

This lead screw specifications: 5 turns per inch, 3/8" outside diameter lead screw, 10 threads per inch and has 2 starts (making it 5 turns per inch). The lead screw is ACME precision and mates perfectly with this anti-backlash nut.

These parts are typically used to stabilize lead screws (so they don't move axially).

This is a 14 tooth 1/2" ID drive sprocket that mates with a #25 roller chain (bicycle chain). With a drive sprocket on a motor and an roller chain, you can make things move.

These sprockets are great for adding to the shaft of a motor to make something move. The drive sprocket will pair with a #25 roller chain.

This is the same sprocket that guides #25 chain and drive sprocket

Notice the very large bore (hole) in the drive sprocket. That bore won't fit any motor generally used in the DIY CNC community, but accompanied with a collar that reduces the bore, now you have a great combination that fits well with 1/4" shafts.

You can use this mechanism to either help position the roller chain to assist the drive sprocket, or be used as a free wheel for one end of a loop of roller chain.

Spring type connecting link for use with single strand chain ANSI number 25. .25 inch pitch.

Spring type connecting link for use with single strand chain ANSI number 40. .50 inch pitch.

This is the chain that mates with the #25 sprockets.

Single strand steel #40 chain

This is an XL size drive pulley with a .2" pitch and a 1/2" bore. Connect these directly to a 1/2" motor shaft and use a .375" timing belt.

Single sided timing belt (belt with trapezoidal teeth) to keep a good position with linear motion applications. Urethane with Kevlar cords, pitch is .08" and the width is 1/4". This item is sold by the inch. Update the quantity with the number of inches desired.

This is an MXL size drive pulley with a .08" pitch. Connect these directly to a 1/4" motor shaft and use a .08" pitch timing belt. Maximum width belt that will fit is 1/4".

Single sided timing belt

This is a drive pulley with a .200" pitch.

These Hiwin spec linear guide blocks are interchangeable with Hiwin manufactured rail blocks.

These rails conform to Hiwin specifications and are interchangeable with Hiwin manufactured rails.

These 20mm Linear Ball Bearing Blocks are made to fit on our 20mm Linear Guide Rails.

We now offer Linear Guide rails made of high-quality hardened steel to add a new dimension of reinforcement to your machine. These rails pair with our 20mm Linear Ball Bearing Blocks.

We use these aluminum rails as guide rails that the v-groove bearings ride along. The aluminum specification is 6061-T6 which is known for its structural characteristics.
