NEEDLE ROLLER BEARINGS ARE ESSENTIAL ON A DAILY BASIS AND IN NUMEROUS SECTORS OF ACTIVITIES AND APPLICATIONS. Wherever compactness is required, where reliability and durability requirements are strong, NTN has the solution in its needle roller bearings offering. With more than 320 million units produced each year, working together with original equipment manufacturers (OEMs) for more than 50 years, NTN has acquired this know-how which are benefiting thousands of customers today.

MOTORISED PORTABLE TOOLS The extreme requirements of this application are reflected in the natural qualities of NTN needle roller bearings: compactness, high load capacity, resistance to overheating (motor) and poor lubrication. NTN is the preferred supplier of the world’s leading professional chainsaws. o In the development of engines, the design of crankshaft bearings and needle roller bearings located at the ends of the rods represents a difficulty: high temperatures, poor lubrication conditions and high loads, in particular due to the very high centrifugal forces. Two-stroke chainsaw...

Recognised by leading manufacturers of two-wheelers, NTN needle roller bearings guarantee perfect safety and exceptional durability. Along all the kilometres, from the motorcycle to the competition sports bike, NTN brings complete peace of mind. o Needle roller and cage assemblies are subject to strong acceleration and a high starting torque during each use. CRANKSHAFT o Needle roller and cage assemblies for connecting rod assemblies withstand high loads due to the particularly severe centrifugal forces. TRANSMISSION o he large speed variations & the impacts in the transmission during gear...

CONSTRUCTION MACHINERY Construction machinery uses a large number of needle roller bearings, all available in the NTN range. Reliability and robustness are the key points sought by users, which is why NTN has been supplying the world’s leading manufacturers for decades. VARIABLE DISPLACEMENT PUMP o This cradle-shaped bearing operates in oscillating motion. It is used to enable the angular movement of the swash plate of the hydraulic pump, which directly depends on the instantaneous flow rate of the pump. In addition to its compactness, the functional accuracy of the bearing ensures...

Towed machines are subjected to rough treatment: impacts, dust, humidity, mud, etc. The seasons follow one another with their share of challenges and it is no coincidence that the extreme robustness of NTN needle roller bearings has impressed the most demanding manufacturers. VERTICAL SPINDLE SHAPER o The complex movement of the arms of the swather is created by the rollers rolling in a cam. In the open version, the bearing and the cam are subject to ingress of pollution. In a sealed housing, the roller will not require any maintenance. It will then withstand the seasons without any...

BOARDING BcgHb L -LJL1 1 1 TTTl In an increasingly demanding industrial world, the operation of machinery and equipment in industrial production and logistics s no longer tolerates shut-downs. Often invisible, NTN needle rollers'^ bearings are nevertheless ubiquitous in factories, as in our daily lives.! By their reliability and durability, they operate unnoticed, guaranteeing1 the operators the proper functioning of their equipment. O The cam follower on a full complement shaft is used to smoothly guide the telescopic part of the tunnel into the first section. The roller then rolls on a...

NTN needle roller bearings are all characterised by their excellent capacity/overall dimensions ratio. To get the most out of their performance, it is important to choose the type of needle roller bearings according to three characteristics of the housing and the shaft: circularity and rigidity, surface condition and hardness.
