Technical Specifications

Bearing 30206 is listed as a component associated with the assembly. Check the product data sheet to see whether it is included with the bearing or must be ordered separately.

30206 bearing compatible with the bearing housing

The CAM199755 bearing is designed for installation using the 30206 bearing. This tapered roller bearing has a bore of 30 mm, corresponding to the specified shaft diameter.

The 30206 bearing is available separately under the Camagris part number:

• 30206 – Tapered roller bearing

A tapered roller bearing consists of several components:

• an inner ring ;
• an outer ring ;
• conical rollers ;
• a holding cage.

Its geometry allows it to support the following simultaneously:

• radial loads caused by weight and lateral forces ;
• the axial loads generated by the disc's working angle ;
• impacts ;
• vibrations ;
• load variations ;
• the forces generated during rotation.

Function of the bearing

The bearing connects the rotating component to its mounting. It holds the shaft in place, guides its rotation, and transmits forces to the machine's frame or arm.

Its main functions are:

• keep the shaft in place ;
• allow for regular rotation ;
• support radial loads ;
• absorb axial forces ;
• maintain alignment ;
• reduce friction ;
• protect the internal components ;
• ensure that it is secured to the flange ;
• transfer the force to the support ;
• Keep the disk or rotating component in the operating position.

A worn bearing can cause play, uneven rotation, and rapid wear on the shaft or disc.

6-hole flange

The CAM199755 clamp features 6 mounting holes. This configuration distributes the forces across several points and ensures that the mounted component is held securely in place.

Before placing an order, be sure to check the following:

• the number of holes ;
• their diameter ;
• their distribution ;
• the center-to-center diameter ;
• the outer diameter of the flange ;
• the thickness of the flange ;
• the type of fasteners ;
• the bearing's position on the machine.

A 6-hole bearing housing may look similar to another model but have a different center distance or different bore sizes.

Center-to-center diameter of 100 mm

The specified center-to-center diameter is 100 mm. It corresponds to the diameter of the circle passing through the centers of the six holes.

This measurement should be distinguished from the distance measured between two adjacent or opposite holes.

To check the assembly:

1. Clean the flange.
2. Identify the center of the six holes.
3. Check their layout.
4. Measure the center-to-center circle.
5. Compare with the value of 100 mm.
6. Also check the diameter of each bore.

A measurement error can prevent the screws from aligning properly.

30-mm shaft

The specified diameter of the shaft is 30 mm. This dimension corresponds to the bore of bearing 30206 specified for installation.

A shaft in good condition must have:

• a smooth surface ;
• a constant diameter ;
• no deep scratches ;
• no significant corrosion ;
• no signs of rotation of the ring ;
• no abnormal shoulder ;
• no damaged threads ;
• No deformation.

If the inner ring has rotated on the shaft, the shaft may be worn even if the new bearing has the correct nominal diameter.

30/30 mm Mounting

The Indication 30/30 mm indicates an assembly with specified bearing diameters of 30 mm. This specification must be verified for both affected areas before placing an order.

The following should be checked:

• the number of bearings used ;
• the part number for each bearing ;
• the diameter of the support spans ;
• the shoulders ;
• the presence of spacers ;
• the correct orientation of the bearings ;
• seals ;
• the adjustment mechanism.

Since the exact number of bearings supplied with the bearing housing is not specified, it should not be inferred solely from the 30/30 mm designation.

• the earth ;
• humidity ;
• mud ;
• projections ;
• vibrations ;
• impacts with rocks ;
• radial loads ;
• axial forces ;
• changes in speed ;
• long-lived assets ;
• corrosion.

The quality of the seals and lubrication directly affects the service life of the bearings.

Symptoms of a Worn Bearing

Replacement may be necessary if you notice:

• play in the disc or rotating component ;
• a rumbling noise ;
• a rumbling ;
• a snap ;
• a difficult rotation ;
• a hard spot ;
• a warm-up ;
• a grease leak ;
• deterioration of the seals ;
• a loose strap ;
• wear on the shaft ;
• irregular rotation ;

• the presence of metal filings.

A seized bearing can prevent the disc from rotating and cause sliding wear.

Common Causes of Deterioration

Bearing wear can be caused by:

• dust ingress ;
• water seepage ;
• a lack of fat ;
• an unsuitable grease ;
• incorrect preload ;
• over-tightening ;
• a game that's too important ;
• incorrect bearing alignment ;
• a worn axle ;
• a deformed flange ;

• loose screws ;
• high-pressure cleaning directed at the joints ;
• prolonged exposure to the outdoors ;
• misalignment of the bracket.

The cause of the failure must be corrected before installing the new bearing.

Inspection of Bearing 30206

When disassembling, check the following:

• the inner ring ;
• the outer ring ;
• the rollers ;
• the cage ;
• the tracks ;
• hair coloring ;
• puncture marks ;
• the presence of corrosion ;
• the game ;
• rotation ;
• signs of overheating.

A bearing that has a hard spot, a scuffed raceway, or a blue discoloration must be replaced.

The inner and outer rings of a tapered roller bearing form a single unit. It is not recommended to install a new ring with a used part.

Adjusting Tapered Roller Bearings

Tapered roller bearings generally require precise adjustment of the clearance or preload.

Overtightening can cause:

• a difficult rotation ;
• a warm-up ;
• rapid wear ;
• degradation of fat ;
• seizure.

If the adjustment is too loose, this can result in:

• of the game ;
• vibrations ;
• a misaligned disc ;
• wear on the tracks ;
• impacts ;
• a gradual loosening.

The method and the setting value must correspond to the equipment's technical specifications Lemken.

Axis Control

The nominal diameter of the shaft is 30 mm. Before installing the bearing, measure the contact surfaces at several points to check for:

• conical wear ;
• ovalization ;
• insufficient diameter ;
• a line ;
• corrosion ;
• a rotation mark ;
• a damaged shoulder.

A bearing that is mounted with too much play can rotate on the shaft and wear out quickly.

Inspection of the holes and the flange

The six holes must retain a uniform shape. Bores that have become oval indicate that the fasteners have been under stress.

Check:

• the six bores ;
• a center-to-center diameter of 100 mm ;
• the bearing surfaces ;
• the flatness of the flange ;
• cracks ;
• traces of movement ;
• the condition of the screws ;
• tightening ;
• the presence of locking mechanisms.

A warped flange can place stress on the bearing or cause misalignment.
