Needle Bearings

TFC is a leading European supplier of Needle Bearings. Needle bearings are a small cylindrical type of roller bearings which are used to prevent friction between moving surfaces which have low rotational speeds. Needle roller bearings are usually used when space is at a premium as needle bearings are much more compact than ball bearings.

With over 40 years experience and with a technical support team available in-house & in the field, TFC are pleased to advise the ideal Needle Bearings for your application.

Needle Bearings Range

Needle roller bearings is a type of bearing that features thin “needle-like” rollers as opposed to the balls that feature on their more famous cousins, ball bearings. This type of bearing is known for its smaller, rigid and more durable design, offering a smaller coefficient of friction, allowing them to transfer motion on rotating surfaces easily.

Components of a Needle Roller Bearing

Needle roller bearings have several components that vary depending on the design of the bearing;

The needle rollers

These are the load-carrying components of the bearing. They are a common component in all needle roller-bearing types. They allow the outer and inner rings to rotate almost friction-free. In most cases, the needle rollers in most cases are manufactured from steel alloy, but we can supply them in other preferable materials as well, depending on the requirements of the project.

Raceways

Not all needle roller bearings have raceways. When present, the raceway serves to guide the roller within the bearing. Naturally, the inner and outer rings are designed to fit closely, but a minimal amount of clearance is necessary to account for variances like thermal expansion. The raceways ensure the rollers don’t skip out of place while under load.

In most bearings, the raceways are made from carbon chromium steel, but other alloys can also be used to improve core features such as hardness, fatigue resistance and dimensional stability.

Cages

Bearing cages separate the rollers to keep the load evenly distributed around the bearing. They also reduce bearing noise, help improve rolling conditions and prevent sliding.

The cages also contain rollers within a single assembly. The most commonly used material for bearing cages is steel. But other materials can also be used where operating conditions permit. Also, some bearings, like the drawn cup needle roller, can be designed without a cage and often come with a full complement of needle rollers. These come with an inward-turned lip to retain the rollers in the bearing ring.

Types of Needle Bearings

TFC supplies various types of needle bearings with varying features to suit different applications and project preferences. Available options include;

Cage needle bearings

Drawn cup needle bearings

This is the most common type of needle bearing. They have a deep but thin-walled outer ring drawn from sheet metal. The bearing bore is commonly left open but can also be capped on one side. The bearing is intended to fit over a shaft and operate smoothly without an inner ring.

Under this type of needle bearing, you will find other sub-types, including the drawn cup with a cage and open ends, the drawn cup with a cage and one closed end and the full complement of bearings with both ends open.

Needle roller bearings

Needle roller bearings are used for higher load-carrying applications and often come with machined rings. They also come in other sub-types, including needle roller bearings with machined rings and inner rings and those without. The bearings without the inner rings are used with hardened ground shafts, while those with inner rings are used in applications where a hardened ground shaft is not feasible.
