The DE Series is a high capacity telescopic rail assembly where the stroke is approximately equal to the overall length of the rail assembly.
This series is constructed with cold drawn steel rails that are hardened to provide long life even in equipment with highly repetitive motion. The bearing system consists of large diameter, caged balls.
The large balls and hardened steel raceways result in high load capacities and long product life.
The DEF Series with threaded attachment holes in each rail is the most popular product.
The 28 and 43 in the part number indicates the overall height of the assembly cross-section in millimeters. Basically the 43 series is the larger heavier duty version of the two sizes.
It has a high load carrying capacity.
Each telescopic assembly consists of three main structural pieces, two small rails on each side of the "I-beam" shaped intermediate element. The smaller rails for the DEF product have drilled and tapped holes spaced every 80 mm for easy attachment.
Periodically applying a small amount of an NLGI #2 lithium-based grease with no solid additives such as MoS2 (molybdenum disulfide) along the rail ball track is recommended for quiet operation and long life.
There are two other versions available: DEV and DEM. The DEV version has unthreaded counter-sunk thru holes. DEM is a version that has threaded holes on one side and unthreaded counter-sunk thru holes on the other. Call for information on these products.
