Roller Bearings(Inner Dia. d:12.700(1/2))
Roller bearings are bearings with cylindrical rolling elements (rollers) placed between inner and outer rings (called races). They are used in a variety of applications such as general machinery, machine tools, motors and reduction drives. The rolling elements used in roller bearings are cylindrical rollers instead of the balls used in ball bearings. Since roller bearings provide more linear support for the load, they are usually used on shafts receiving higher loads. The types of roller bearings available include cylindrical roller bearings and several others. For example, needle roller bearings are more suited to space-saving applications than cylindrical roller bearings. Conical roller bearings can support a radial load and unidirectional axial load at the same time. Self-aligning roller bearings enable the inner race, rolling elements and retainer to rotate in a tilted posture relative to the outer race, making them suited to use in applications such as machinery with highly flexible shafts.

Shell-Style Needle Roller Bearing
NTN
[Features]
· Bearing includes a needle roller and cage installed following formation of an outer ring from a thin steel plate via precision drawing and surface curing of the corresponding raceway. (For model numbers with "M" in the suffix symbol, curing is performed after installation).
· Allows for space and cost savings and has the lowest section height of any bearing which includes an outer ring.
· Generally, designs which use the axis as a raceway directly do not include an inner ring.
· Structured so that the outer ring needle roller and the retainer do not separate, and handling is simplified as the bearing is only press-fixed to a rigid housing and no stop ring for performing fixing in the axial direction is required.
