Elevator Bearing Blocks

The Elevator Bearing Blocks family offers reliable, versatile solutions for creating linear motion in elevator systems using MAXTube. Both the original Elevator Bearing Block and the Clamping Elevator Bearing Block provide teams with the flexibility to design efficient, high-performance elevators within the REV ION Build System.

The Elevator Bearing Block (REV-20-2051) is a trusted choice for smooth sliding motion between two pieces of rectangular tubing. It mounts on the narrow, 1in side, of tubing (e.g. 1x1 or 2x1) and uses shielded ball bearings for reduced friction. Its self-locating aluminum blocks simplify assembly, making it ideal for traditional elevator systems.

The Clamping Elevator Bearing Block (REV-21-2636) improves upon the original design. Clamping onto the sides of MAXTube, it enables mounting along any length of a 1in side of MAXTube. It features integrated nut pockets for adding steel threads if the aluminum ones wear out or if access to screw heads on the same side is desired. With a reduced tube spacing offset of 0.5 inches, it provides an overall more compact linear motion solution, while a large one-sided keying feature prevents alignment issues. The mounting hole pattern follows the REV ION standard, with two additional mounting points to reduce twisting over time. Enhanced with larger bearings and dual face-contact bearings, this block delivers nearly double the dynamic load capacity of its predecessor, making it a robust yet flexible option for teams incorporating custom parts or maximizing stiffness.

Whether you choose the Elevator Bearing Block for a simple solution or the Clamping Elevator Bearing Block for enhanced performance, both ensure smooth, reliable operation for competitive robotics and enable easy assembly with innovative features.

Features

• Elevator Bearing Block
  • Shielded ball bearings provide support in the lateral and thrust axes
  • Aluminum blocks are notched to self-locate on the side of rectangular tubing
  • Individual bearings support the lateral and thrust axes for further reduced friction
  • Aluminum blocks on either side of the tubing support the bearings for easier assembly
  • 0.75” spacing between the tubes of each stage
• Clamping Elevator Bearing Block
  • Integrated nut pockets for easy maintenance and assembly
  • More compact tube spacing offset from 0.75in to 0.5in compared to traditional elevator bearing blocks. Leading to increased stiffness
  • Large one-sided keying feature to prevent alignment issues
  • Reorientated and standardized mounting hole pitch to give teams sturdy mounting without modifying tubing
  • Almost doubled dynamic loading of side bearings compared to traditional blocks due to selection of larger bearings
  • Increased amount of face contact bearings from 1 to 2 per clamping block
  • Bearing retention with standard #10-32 and M3 hardware for ease of repair
  • 0.5” Spacing between the tubes of each stage
