BGL OHE31/500HT hydraulic sleeve

BGL OHE31/500HT belongs to hydraulic sleeve, part of our Bushings and sleeves range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for OHE31/500HT and any equivalents.

A hydraulic sleeve from the BGL OHE HT line sits between shaft and housing and carries oil channels that let pressurized oil reach the contact surfaces. The resulting film cuts friction so the assembly can be seated and, more importantly, released again on medium and large shafts. Typical duty is power transmission and heavy equipment where the fit has to hold firmly yet come apart without scoring the mating surfaces.

Reading the code helps when you order. OHE marks the series with oil channels, and HT tells you the injection channel sits on the outer side. The figure in the middle is the bearing bore in millimeters, so OHE31/500HT points to a 500 mm bore, with the shaft slightly under that. Channel position is what separates OHE HT from other variants, since it decides where oil enters during mounting and dismounting.

These sleeves turn up in process industries, steel, cement, mining and paper, wherever shaft diameters are large and maintenance windows are tight. Gearboxes, mills, presses and other large machines use them as well, in plants that need high torque through a fit that can still be removed rather than one locked in place by interference that later makes takedown difficult.

Selection comes down to shaft and housing diameter, the torque to be transmitted and the oil injection method on hand. Clean the surfaces first, use a compatible oil and a manual or hydraulic pump to build pressure. Shaft and housing must line up; misalignment creates point loads and early failure. Injection pressure and tightening sequence should follow the manufacturer's instructions.

When checking equivalents from other brands, compare the full designation: diameter, channel type and suffix. A sleeve with an outer channel does not swap for one with an inner channel unless the mounting direction is confirmed. If you only have another brand's code or an unidentified part, send the data and we will point you to the compatible alternative, since interchangeability rests on dimensions and channel function, not diameter alone.
