Cylindrical roller bearings | SKF

The bearings can meet the challenges of appliions faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life. Cylindrical roller bearings are also available in sealed or split designs.

CYLINDRICAL ROLLER BEARING ALOG

The tapered roller bearing’s most important dimensions are: • The outside diameter of the outer ring, or cup, is known as the O.D. (D). The other basic dimension of this part is the cup width (C). Both are important for fitting the bearing onto the housing. • The inside diameter of the inner ring, or cone is called the bore (d).

Precision Needle Roller Bearings - Inch and Metric | AST

Needle roller bearings are essentially cylindrical roller bearings except that their cylindrical rollers have a length 3 to 10 times their diameter (versus less a length less than 3 times their diameter). Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity.

Bearing selection for low-speed appliions | Kaydon

As Fig. 1 shows, a low-speed bearing with a pitch line diameter of less than 1.9 inches can rotate as fast as 1,000 rpm. If, on the other hand, the pitch line diameter is much larger—say, 65 inches—the bearing is considered a low-speed bearing only when the angular speed is less than 30 rpm. Figure 1.

JOURNAL BEARING DESIGN TYPES AND THEIR …

The reason for such a large selection of bearings is that each of these types has unique operational characteristics that render it more suitable for one appliion than another [1,2,3,4,5]. The fundamental geometric parameters for all journal bearings are diameter, pad arc angle, length-to-diameter ratio, and running clearance.
