These aluminum 5M HTD Pulleys work great for creating belt reductions directly off the motor. Use a 15mm wide belt or two 9mm wide belts as the inside pulley teeth are 18.5mm wide. Choose either 8mm keyed bore or spline bore depending on the motor type you're using.

Tired of hex clamp collars that cost an arm and a leg? Tired of stripping out the set screw on your clamp collar? Need to add a collar in an assembly and don't want to remove everything from your hex shaft?

Me too! I've ran into all of the above scenarios multiple times building multiple robots. These collars are the holy grail -

• split so they can easily be added or removed
• lightweight 6061 aluminum
• .5 oz (.031 lbs) for one hex collar
• uses two 8-32 socket head cap screws that require a 9/64" allen wrench
• $4.00 per collar, sold in 5 packs
• anodized black for awesomeness

General Dimensions:

• When clamped on 1/2 inch hex shaft - approx 1.2 inch outer diameter
• 0.40 inches wide

This turnbuckle chain tensioner integrates directly with #25 chain. Using a chain tool, the custom 1/4-20 link bolts replace a chain link and have the pin pushed back through it to become part of the chain. Then simply twist the center coupler to tighten or loosen the chain and tighten the jam nuts once your chain tension is perfect.

All parts are made of steel including the coupler and the custom chain link bolts are 1/4-20 thread for increased strength. One link bolt is left hand threaded and the other is right hand threaded, so take care not to mix them up if purchasing multiple sets.

Material: Steel, all of it.

The Thrifty Clamping Bearing Block provides teams a quick and easy way to capture 1.125" OD flanged bearings when mounting to 2" x 1" or 1" x 1" box extrusion. Simply drill a pass thru clearance hole and insert the bearing which is then trapped against the extrusion wall's material.

Features include -

• Clamps around 2" x 1" or 1" x 1" extrusions
• Two counterbored 10-32 holes 2" apart allow for mounting of planetary gearboxes or 2" bolt circle motors
• #8 holes on a 1.875" diameter bolt circle allow for usability in existing FRC applications
• 6061 Aluminum material anodized black

Kit includes:

- Two black anodized plates

- Four 10-32 1.5" long button head bolts

- Two 10-32 0.50" long bolts

Bearings are NOT included with this kit

Mount all the things with this latest offering from The Thrifty Bot! Finally a plate that can interface with just about any common motor or planetary gearbox in the FIRST Robotics Competition. This 4mm thick 6061 aluminum black anodized plate includes bolt mounting patterns for the following motors and planetary gearboxes:

- REV Ultraplanetary Gearbox

- REV NEO 550 & Banebots 550 Brushed motors

- VEX Versaplanetary and Versaplanetary Lite gearboxes

- AndyMark 57 Sport planetary gearboxes

- 775 series brushed motors

- REV NEO & Falcon 500 brushless motors

- Traditional Mini-CIM & CIM motors

- 4mm thick (.157") allows for stronger cantilevered applications

- 1/4" hole to hole spacing, 1/2" spacing between hole rows. Holes are .164" natively supporting #8 bolts or 5/32 rivets. Holes can be drilled out to support #10 hardware.

The original vectored intake wheel, now with even more options. This wheel design was battle tested and match proven on many FRC robots during the 2020 season. These wheels help with redirecting game objects while imparting lateral force, helping to move game pieces either left or right in the direction you desire.
