EWELLIX Linear ball bushing Open LBHT 20 A

Linear ball bearings are available in compact LBB range (ISO series 1) and standard LBC range (ISO series 3). Series 3 linear ball bearings include the advanced cylindrical LBCR and LBCT design, the self-aligning LBCD and LBCF design and the LBHT design with extra high load carrying capacity. The bearings consist of a polymer cage with steel raceway segments to guide and recirculate the ball sets within the complete cage. Any of the bearings in the ISO series 3 are available in a standard and corrosion resistant version, with an integral double lip seal to provide maintenance-free operation under normal conditions. These linear ball bearings are interchangeable with all former series 3 bearings.

Type LBHT
Heavy duty open design linear ball bearing (ISO series 3) available diameter from 20 to 50 mm. Ultimate size and performance ratio with maximum load ratings. Made for long distance strokes with supported shafts. LBHT linear ball bearings are used in applications where several shaft supports, or a continuous shaft support is needed to prevent shaft bending. Due to the open design of the LBHT bearing, one raceway segment is eliminated. However, this does not have a significant effect on its load carrying capacity. The raceway segments of the LBHT have been optimized so that it has the same number of raceway segments as a closed design bearing. Unlike other open design linear ball bearings, these bearings feature a shoulder in the cage on each side of the opening which acts like a gap-type seal. The sealed variant is fitted with integral double lip seals. These seals have an inner lip to keep lubricant in the bearing; the outer lip acts like a wiper seal to keep contaminants out of the bearing. Unsealed bearings are fitted with non-contacting shields to protect the bearing from large contaminant particles. LBHT linear ball bearings are also available with stainless steel balls and raceways for wet or corrosive environments. The stainless steel variant is identified by a HV6 suffix in the designation.
