Cylindrical Roller Bearings FAG NJ236 -E-XL-M1-C3
The FAG NJ236 -E-XL-M1-C3 cylindrical roller bearing offers a high radial load capacity with an 180 mm bore, a brass cage and increased C3 clearance.
The NJ236 -E-XL-M1-C3 cylindrical roller bearing is designed as a single-row rolling bearing for demanding radial loads. This version has an outer diameter of 320 mm and a width of 52 mm. Thanks to its solid brass cage, this variant is suitable for environments subject to vibration or fluctuating speeds. As an open bearing, it can be flexibly integrated into existing lubrication systems.
What is the NJ236 -E-XL-M1-C3 cylindrical roller bearing suitable for in operation?
This radial roller bearing is primarily used for high radial loads. As cylindrical rollers have line contact, they can accommodate high radial forces. Thanks to the NJ design, the bearing functions as a support bearing. In addition to radial loads, it also accommodates one-sided axial forces and allows axial displacement in the opposite direction. The inner ring can be removed from one side, which facilitates the separate assembly of the shaft and housing.
What are the characteristics of brass cages and C3 clearance?
The version with the suffix M1 features a solid brass cage. This cage is designed to withstand thermal loads and acceleration forces. The designation C3 indicates a slightly increased radial bearing clearance. This additional radial clearance compensates for temperature-induced expansion of the shaft and housing. This ensures that the bearing continues to function correctly within the specified temperature range of -30 to +150 degrees.
What are the main dimensions of the NJ236 -E-XL-M1-C3 cylindrical roller bearing?
The main dimensions are 180 mm internal diameter, 320 mm external diameter and 52 mm width. These standardised dimensions enable a precise fit when installed on suitable shaft seats and in standardised bearing housings.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
A characteristic feature of the NJ design is the presence of two fixed shoulders on the outer ring and one fixed shoulder on the inner ring. This allows the unit to act as a support bearing that guides shafts in the axial direction. Axial movement in the opposite direction remains possible, which facilitates installation and accommodates thermal expansion.
Why is the increased clearance C3 relevant here?
The designation C3 indicates radial bearing clearance that exceeds the standard range. In bearings of this size, temperature differences between the inner and outer rings frequently occur during operation. The increased radial clearance helps to ensure that the components do not become unduly stressed when they heat up.
What operating temperatures is this model designed for?
The specified temperature range is between -30 and +150 degrees. The solid brass cage and the open design, which does not feature any temperature-sensitive contact seals, are designed for operation within this temperature range.
What tolerance class does the NJ236 -E-XL-M1-C3 bearing meet?
This version is manufactured to tolerance class P0 or PN, which corresponds to ABEC 1 in the international standard. These dimensional and concentricity tolerances meet the standard requirements for general mechanical engineering.
Is the cylindrical roller bearing sealed or open?
The model is designed as an open bearing without an integrated seal. Protection against contamination and lubricant loss must be provided by the housing environment as a design feature. As the outer ring has no lubrication groove or lubrication bore, the lubricant is supplied from the side of the rolling elements.
