Split plummer block housings, SNL and SE 2, 3, 5 and 6 series
SNL and SE plummer block housings are the most popular SKF bearing housings on the market, developed to be the first choice for design, quality and economy.
SE plummer block housings are a new generation with a number of new features and a stronger material grade. They are available from size 507 up to and including 515-612.
SNL and SE plummer block housings enable the incorporated bearings to achieve maximum service life with less need for maintenance. Different housing variants and seal designs are available, making the use of tailored housings virtually unnecessary and enabling costeffective bearing arrangements to be made.
