Cylindrical Roller Bearings FAG N308 -E-XL-TVP2
The FAG N308 -E-XL-TVP2 cylindrical roller bearing, measuring 40x90x23 mm, offers a high radial load capacity as a separable non-locating bearing with a polyamide cage.
The FAG N308 -E-XL-TVP2 cylindrical roller bearing, as a single-row radial roller bearing, withstands high radial forces. In the N design, the inner ring has two fixed flanges, whilst the flangeless outer ring is designed to be removable from both sides. This design facilitates the separate installation of both bearing rings. This version is suitable for machine components where axial changes in shaft length are compensated for directly within the bearing arrangement.
What is the N308 -E-XL-TVP2 cylindrical roller bearing suitable for as a floating bearing?
This floating bearing is suitable for shaft mountings where thermal expansion or manufacturing tolerances require free axial compensation. As the outer ring has no flanges, the shaft can be moved axially relative to the housing. Typical applications are found in general mechanical engineering under purely radial loads. The open bearing requires lubrication via the surrounding structure, as the outer ring is manufactured without a lubrication bore or lubrication groove.
What is the function of the TVP2 polyamide cage in the N308 cylindrical roller bearing?
The polyamide cage, designated TVP2, guides the cylindrical rollers whilst having a low mass itself and ensures smooth running. The elastic plastic material is characterised by favourable friction coefficients. The permissible temperature range of -30 to +120 degrees must be observed for use. The standard radial clearance, in conjunction with tolerance class P0, contributes to smooth running under normal operating conditions.
What are the dimensions of the N308 -E-XL-TVP2 cylindrical roller bearing?
The bearing has an internal diameter of 40 mm, an external diameter of 90 mm and a width of 23 mm. These standardised key dimensions allow it to be fitted into standardised housing bores and onto corresponding shaft seats in industrial machinery and plant engineering.
What are the characteristics of the N series for this cylindrical roller bearing?
In the N design, there are two fixed flanges on the inner ring which guide the rollers and cage laterally. The outer ring is completely flangeless and can be removed from either side. As a result, the bearing functions purely as a non-locating bearing and accommodates radial loads only.
What does the suffix ‘TVP2’ mean in the N308 cylindrical roller bearing?
The abbreviation TVP2 denotes a polyamide cage. This material is characterised by its low weight, good sliding properties and damping characteristics. The cage guides the rolling elements with minimal vibration and is suitable for operating temperatures of up to +120 degrees.
What is the operating temperature range for the bearing?
The N308 -E-XL-TVP2 cylindrical roller bearing is specified for an operating temperature range of -30 to +120 degrees. This range is largely determined by the polyamide cage fitted. When designing the system, care must be taken to ensure that the lubricant used is also suitable for this range.
What is the clearance of the N308 -E-XL-TVP2 cylindrical roller bearing?
The roller bearing is manufactured with a standard radial clearance. This design is suitable for typical installation conditions, fit selections and operating temperatures where no increased thermal expansion or high preload is to be expected.
What tolerance class does the N308 -E-XL-TVP2 cylindrical roller bearing meet?
The bearing complies with tolerance class P0 or PN, which corresponds to the international ABEC 1 classification. This represents the standardised precision requirements regarding dimensional, form and running tolerances for industrial applications.
