Distributor Bearing Wholesalers Inc electrification, automation and digitization are Distributor Bearing Wholesalers Inc' long-term growth areas. In order to fully tap the market potential of these areas, we will be integrated into nine business groups. SL Type Cylindrical Roller Bearings NTN is an independent operating part.
Power Generation and Natural Gas Group is a trusted partner with world-class products and solutions. Distributor Bearing Wholesalers Inc helps Chinese customers successfully operate thermal power plants and help them cope with specific economic and ecological challenges in China's market environment.
Distributor Bearing Wholesalers Inc supplies many sizes of SL Type Cylindrical Roller Bearings NTN with integral radial shaft seals at both sides. They are available in several designs depending on bearing size as well as on the open (non-sealed) basic design.
Whenever possible, Bearing SL02-4930 should be used for rolling mills. Compared with open bearings they offer the following advantages
longer service life
reduced grease consumption (by up to 90%)
extended maintenance intervals
grease is retained within the bearing
less surplus grease to contaminate the milling emulsion, to improve both the rolling process and product quality
reduced environmental impact.
Bearing SL02-4930 can simply replace open bearings as part of a rebuild or refurbishment because the boundary dimensions are the same.
Bearing SL02-4930 are fitted with specially designed, C-shaped, radial shaft seals on both sides. This enables the bearing to incorporate rollers that are equal to, or just slightly shorter than the rollers used in an open bearing. Consequently, the load carrying capacity of a Bearing SL02-4930 is the same or very similar to an open bearing. The seals permit high sliding velocities and are intended for operating temperatures between –20 and +140 °C.
Distributor Bearing Wholesalers Inc Explorer SL Type Cylindrical Roller Bearings NTN have sheet steel reinforced radial shaft seals made of hydrogenated acrylonitrilebutadiene rubber (HNBR) that are snapped into the groove in the outer ring.
Standard bearings contain sheet steel reinforced seals made of fluoro rubber (FPM) that must be staked into a groove in the outer ring. Fluoro rubber seals require special handling.
O-rings inserted in grooves in the outer ring outside surface prevent dirt or water from entering between the outer rings and the chock bore that otherwise would contaminate the lubricant.
Standard TQOSN design Bearing SL02-4930 are supplied with window-type, stamped steel cages, without spacer rings. However, spacer rings are available in the TQOS design.
Larger size Bearing SL02-4930 in the TQOSN.1 design are for applications that require extremely high load carrying capacity. These bearings have a special pin-type steel cage that uses pierced rollers. SL Type Cylindrical Roller Bearings NTN are also produced with extended inner rings which can serve as counterfaces for radial shaft seals. These bearings are supplied as standard without spacer rings in the TQOESN design or with spacer rings in the TQOES design.
