HOLK's SED Plummer Block Housings (SED 30, 31, 32, and 39 series) are large split bearing housings designed to accommodate heavy loads acting perpendicular toward the support surface within an angle of ± 55°. These types of loads are typically encountered in conveyors, mills and crushers. 

SED series plummer blocks are big symmetrical, split bearing housings consisting of a housing base, cap and two split covers. The covers are bolted to the base/cap with hexagon head bolts on each side. The bearing housings have eight drilled attachment bolts holes in the base as standard. Two cast holes in the cap facilitate handling. The SED housing series consists of six different housing bodies. Each housing body can accommodate multiple bearing series and sizes. 

SED plummer block housings are made of spheroidal graphite cast iron(Ductile Iron). Other material like Cast Steel is also available upon request. 

The dimensions of SED bearing housings are not standardized either nationally or internationally. In addition to standard design SED housings, a number of variants are also available at HOLK.
