Compact S-Beam Load Cell | Tension & Compression | DBCR
A Slim, Compact, and Precise, Miniature S-Beam Load Cell The DBCR compact S-beam load cell is suitable for use in both tension and compression and lends itself to a multitude of low-range monitoring, control, test and measurement applications including material testing machines and small suspended hoppers. The DBCR is a compact version of the classic S-beam load cell design manufactured from aluminium and available with measuring capacities from 0-10N up to 0-500N. It offers a very high accuracy of better than 0.05% of rated capacity. The DBCR compact S-beam load cell can be supplied calibrated with any of our range of strain gauge input instrumentation to provide a complete, ready to use measurement system. For other sizes and capacities please view our full range of S-Beam load cells.

Mounting And Installation Accessories
Load Buttons and Rod End Bearings
Designed to align forces through the principal axis of the load cell thus reducing the effects of extraneous forces, hence offering improved performance from the cell. Load buttons are used where compressive forces are applied. Rod End Bearings are used where tensile forces are being applied.

Rod End Bearings for Tension Use
Maintenance-free rod ends are a complete units made up of a housing with both an integral shank (with an internal or external thread) and a maintenance-free spherical plain bearing, located within the housing. Key Features:
- Supports radial loads in a tensile or compressive direction.
- Suitable for unilateral loads – can support alternating loads and alternating loads in combination with bearing GE..UK-2RS, please consult sales.
- Zinc plated for corrosion resistance.
- Are maintenance-free.
- Fitted with radial spherical plain bearings GE..UK
- Hard chromium/PTFE composite sliding contact surfaces.
- Enables compact adjacent construction thanks to its thin walled design of the eye housing.
