This mounted unit pairs a cast iron Y housing with an NSK ball insert bearing that arrives already sealed and greased. It holds a rotating shaft in place and, in the JELPT line, also lets you set belt or chain tension. Maintenance and purchasing teams use it where installation is quick and alignment is straightforward. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in Latin America.

Reading a JELPT code: the prefix tells you it is a tensioner housing with an insert bearing, the number that follows gives the nominal shaft diameter for that particular code, and the W3 suffix appears on every code in the series and covers the sealing arrangement together with the tensioner thread. Codes written with a hyphen and three digits express dimensions in either inches or millimeters, depending on the standard behind them.

Typical duty covers belt conveyors, packaging lines, belt drive systems, agricultural equipment and similar machinery. In these positions the unit keeps the shaft aligned and applies tension to the belt or chain, which cuts vibration and wear. Because the bearing comes lubricated and sealed, upkeep stays simple in dusty or damp areas. Many plants order these units both for new projects and as drop-in replacements.

Sizing starts with the shaft diameter, then the mounting style and the room you have around the unit. Check that the insert bearing's sealing suits the environment; W3 versions normally carry lip seals that hold grease in and keep contaminants out. Set the base level during installation and avoid hammering on the insert. Lubrication for life is typical here, though harsh conditions may call for extra sealing.

Units from different makers can be swapped as long as the key dimensions line up: shaft diameter, hole spacing and height to center. NSK, SKF, FAG, NTN and others list equivalents, but suffixes for sealing or thread can differ. Compare those critical dimensions and the tensioner style before replacing. Send the original part code and we will point you to a compatible option.
