Roller bearings are available with the grooved race in the outer and inner members. Roller bearings are capable of carrying the journal (radial) loads. It can work with greater load than ball bearings. To use this bearing, race is required to be locked. On the basis of uses, roller bearings are classified in following types.

Needle roller bearing is a special type of roller bearings that has cylindrical rollers that resemble needles because of their small diameter. Normally, the length of rollers in roller bearings is only slightly more than its diameter. When it comes to needle bearing, the length of rollers exceeds their diameter by at least four times.

and o-ring. Whenever a shaft rotates, it needs a bearing arrangement for smooth, effective operation. Wherever there's a bearing, you'll find a seal helping it to reach its maximum service life and reliability. In simplest terms a shaft seal is a barrier with four functions: 1) Retaining lubricants or liquids 2) Excluding contaminants 3)

In ring rolling, a ring of small diameter workpiece is rolled between two rollers to form a ring of larger diameter. One roller is the drive roller, while the other roller is idle. An edging roller ensures that the metal will have a constant width. The reduction in width of the ring is compensated for by the diameter of the ring.

Mullen Mouth Snaffle. This is the only common snaffle bit that does not have any joint at all. With its slight curve, it is often considered to be a mild bit because it puts more pressure across the tongue instead of the more sensitive bars. However, for that reason it is not typically a bit that will aid in the lateral flexion of a horse's head.
