Cam followers

Nadella cam followers are designed to rotate directly on cams, flat surfaces or guides. In order to meet the unusual conditions of use - significant loads accompanied by substantial and repeated shocks - these types of bearings have the following characteristics:

• Heavy section outer ring, to support the load and minimise the risk of deformations that reduce the bearing's load-supporting capacity.
• Rolling or cup needle roller bearing, with cage or full complement to guarantee maximum load capacity.
• Outer profiled ring to compensate for parallelism errors between the roller and track or cylindrical ring to reduce contact pressure with the sliding surfacex.
• Lubrication hole with output under the needles to restore the grease through the axle.

The cam followers with stud can be equipped with an eccentric collar to adjust the pre-load during assembly. They can be equipped with synthetic or metal seals to retain the grease.
In standard range of NADELLA cam followers there are:

• Cam followers with stud GC.. MINI: Full complement needle rollers with outer diameter up to 15mm. The mini roller which thanks to the needle roller bearing has the highest load/diameter capacity ratio. 
• Cam followers with stud GC.. SW: Full complement needle rollers with outer diameter from 16 to 90 mm. This is the classic Nadella cam follower with stud updated with the extension of the adjustment hexagonal socket on each end and for all dimensions.
• Cam followers with stud KR.. EE: Cam followers with roller cage and outer diameter from 16 to 90 mm. The classic cam follower with cage, they are suitable for less demanding applications but with elevated speed.
• Full complement rollers GCU: Full complement needle rollers with outer diameter from 35 to 130 mm. The roller solutions instead of the needles reduces the thickness of the outer ring and the number of rollers.
• Mini cam followers without stud FP: Full complement needle rollers with outer diameter from 10 mm to 15 mm. The mini roller which thanks to the needle roller bearing has the highest load/diameter capacity ratio.
• Full complement needle rollers FG.. SW: Full complement needle rollers with outer diameter from 16 to 250 mm.
• Full complement rollers FGU: Full complement rollers with outer diameter from 35 to 300 mm. The heavy series differs from the light series in the thickness of the outer ring, from which a greater outer diameter derives and the ability to sustain more significant loads.
• Full complement needle rollers RNA 11000: Ring with full complement of needle rollers, mechanically fastened and separate inner ring. Outer diameter from 19 to 90 mm.
• Cam followers with pivot and tapered bearings PK: Cam followers without stud with high load capacity and tapered roller bearings. Outer diameter from 52 to 110 mm and they absorb the axial thrusts due to the misalignments between the cam follower without stud and rolling track without compromising the function of the cam follower without stud.
• Guide wheels FK: Cam followers without stud with high load capacity and tapered roller bearings. Outer diameter from 52 to 110 mm and the width of the sleeve allows for the strain to be distributed on a wide contact surface with the rolling track.
• Cam followers with heavy stud PFL: Cam followers without stud with high precision and load capacity with outer diameter from 10 to 22 mm. With heavy stud and careful construction for use on automatic machinery, positioners and cam movements.
• Double cam followers with stud PFDL: Outer diameter from 24 to 32 mm This is the ideal solution in the applications in which the cam is strained in alternating direction.
