Roller Bearings. Roller & Cylindrical Bearings are a type of rolling-element bearing that uses cylinders (rollers) to maintain the separation between the moving parts of the bearing (as opposed to using balls as the rolling element). The purpose of cylindrical bearings is to reduce rotational friction and support radial and axial loads.
Dalton Bearing offers many roller bearing solutions to meet customer demands and application requirements. Dalton Bearing offers roller bearings from some of the most recognized names in the business such as NTN, SNR and many others. Dalton Bearing can meet the roller bearings demands of any size customer in a wide array of different industries.

A roller bearing has two grooved tracks, but instead of balls, roller bearings utilize rollers. The rollers may be cylindrical, spherical or tapered. If the rollers are cylindrical, only radial loads (perpendicular to the axis of rotation) can be carried, but with tapered or spherical rollers both radial and thrust loads can be carried.
Roller bearings perform better under shock and impact loading. Ball bearings are usually sold as assemblies and are simply replaced as units. Roller bearings can often be disassembled and the roller carrier and rollers, or the outer or inner races, replaced individually. Rear-wheel-drive cars use such arrangements for the front wheels.
Cylindrical Roller Bearings. Motion has an extensive inventory of cylindrical roller bearings available for purchase. Bore types include straight, cylindrical, tapered, and more. Multiple options for bore diameters, outside diameters, and overall widths. Sorted by:
Roller bearings have high radial load capacity and some designs can accept light axial loading. They operate at moderate-to-high speeds. The lubrication method must be carefully considered during the design phase when using roller bearings.
A needle roller bearing is a special type of roller bearing which uses long, thin, cylindrical rollers resembling needs. Their rolling elements are small in diameter and long in length. Needle roller bearings are compact in size, can carry high radial loads and have limited speeds.

Needle roller bearings support high speed, high radial loads in confined spaces. Spherical roller bearings support heavy shock loads where misalignment is a risk, such as wind turbines, pumps, paper processing, and fans. Tapered roller bearing cones and cups support high radial and axial loads and are used for such things as axels and gear boxes.
Roller bearings are any cylindrical or spherical object that aids in the movement of an object greater in size than the bearing itself.
The bearing setting of a roller bearing is defined as the specific amount of either endplay or preload. Tapered roller bearings have the inherent advantage of being adjustable; therefore, they can be set to approach optimum performance in almost any application. They may be set manually, supplied as a preset assembly, or set by using an ...

Rolling bearings Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.
Roller Bearings. Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing. They are usually located at the ends of the turbine and compressor shafts and are often mounted in a ...

This type of bearing is composed of an inner ring, outer ring, and tapered rolling elements. Thanks to the geometry of their design, tapered roller bearings can withstand combined loads (axial and radial). In addition, this design allows rolling movement without the rollers slipping off the tracks of the outer and inner rings.

Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline values these effects become particularly noticeable. The values are not valid for bearings of the NUP design or the NJ design with an HJ angle ring.

Needle Roller Bearings. Needle bearings use small needle rollers (6mm or less in diameter) as rolling elements. These bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They're designed to withstand oscillation, perform ...
Roller bearings, compared with equivalent sized ball bearings, can handle generally higher loads, at generally lower limiting speeds. Also, given the same load rating, roller bearings are generally more compact than ball bearings. The Enduro roller bearings listed here are of two types: 1. MR series, with their corresponding MI series inner rings.
smaller bearings to carry a given load or a given-size bearing to carry a higher load. • Thrust load capacity is poor because any thrust load would be applied to the side of the rollers, causing rubbing, not true rolling motion. Needle Bearing • Needle bearings are actually roller bearings, but they have much smaller-diameter rollers.
