Table 2 Cages – split cylindrical roller bearings Bearing series Material Polyamide Brass Medium carbon steel Die cast or machined aluminium alloy 100 Standard for d ≤ 150 mm or 6 in. Standard for d > 150 mm or 6 in . – – 01, 02, 03/03E – Optional – Standard 01E – Standard for d > 105 mm or 4 in. Standard for d ≤ 105 mm or 4 in . – 02E – Standard for d > 150 mm or 6 in . – – 04 series bearings • are light duty • are manufactured as – locating bearings (designation suffix GR) – non-locating bearings (designation suf- fix EX) • are suitable for high speeds • can be modified to omit the high speed features as an economical solution for slow speed applications • can be customized and modified to suit specific application requirements • are available on request Some popular 04 series bearings are shown in the product table on page 100 . Standard assortment • four different series ( table 1 ): – 100 series: compact (for high speeds) – 01/01E series: medium duty – 02/02E series: heavy duty – 03/03E series: very heavy duty • fitted with one of the cages shown in table 2 Large size bearings • have a bore diameter d > 600 mm ( 24 in. ) • are manufactured as: – locating bearings (designation suffix GR) – non-locating bearings (designation suf- fix EX) • can be customized and modified to suit specific application requirements • are available on request Some popular large size bearings are shown in the product table on page 98 . The infor- mation is provided as a guideline only as the bearings are often modified to suit specific application requirements. Bearings in the extra expansion design (designation suffix EXILOG) typically have different overall dimensions compared to the standard large size bearings. Other bearing options are also available, as outlined under Designations on page 186 . Housings Split cylindrical roller bearings are suitable for various housing types, the most common being: • plummer block housings ( product tables , page 108 ) • flanged housings ( product tables , page 150 ) For large size bearings, SKF can supply suit- able standard housings including cartridges as well as customized housings on request. For existing housings, mounting tolerances are also available on request. Typically, 04 series bearings are mounted in housings integrated in the structure of the machine. SKF can manufacture housings on request. Internal clearance • Normal for temperatures up to 100 °C (210 °F) provided the difference between the shaft and housing temperature is not more than 40 °C • C3 and C5 for higher temperatures or greater temperature differentials • reduced clearance (C2) for specific applica- tions, e.g. for reciprocating or vibratory applications Internal clearance 71 2
