No RPM Limit FE 8000 Series
A unique "non-lift-off" design without drag clips ideal for automotive builds or performance racing.
No built-in ball bearing support. Has no RPM limits & Supports high torque needs: 609 to 14,060 Nm. Bore (ID) sizes: 38.09 to 220 mm (1.499 to 8.66 in)
Backstopping Clutch with Mounting Tab
This heavy-duty clutch (aka a hold-back clutch) is good for high torque operations and ensures motion freezes in place. Bore (ID) sizes: 15 to 40 mm. (0.59 to 1.73 in)
Roller Ramp Clutches
Designed for HEAVY-DUTY applications that require tough durability.
CF Seals
The best protection for your bearing. Easy to install with a simple “drop-in” next to your bearing. No added space needed. CF seals offer 100% sealing efficiency against splashing liquids.
L Seals
Protection against low contamination & splashing liquids.
M Seals
Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.
S Seals (Gap Seals)
Our GMN Gap Seals are plastic and a great choice for washdown applications, such as food conveyors and food manufacturing facilities
Angular contact bearings support both radial and axial loads and are designed to operate at high speeds for vast amounts of time. Also known as spindle bearings, GMN angular contact bearings are beneficial for applications that:
Our ABEC 7 angular contact bearings are manufactured in Nürnberg, Germany, and stocked in Houston, Texas. We have one of the largest in-stock inventories of angular contact bearings in N. America.
We are a precision bearing company located in Houston, Texas, and the only authorized distributor of GMN precision components in the USA.
Our three angular contact bearing product lines include our Standard (S), SM, and KH series.
We ship orders the same day the PO is sent (as long as the PO is sent by 3:30 pm CST). Most of our precision bearings are in stock and ready to ship out from Houston, Texas.
Fast Speeds, Heavy Loads
The S “standard” series bearing adapts to many different speeds, loads and other variables.
This series fits shafts with a max ID of 120 mm and supports max RPM speeds of 195,000 (steel) / 243,750 (ceramic).
Faster Speeds, Medium Loads
Compared to our S Series, the SM can support speeds about ~ 20% faster w/ medium loads.
The SM series fits shafts with a max ID of 120 mm and supports max RPM speeds of 230,000 (steel) / 287,500 (ceramic).
Fastest Speeds, Light Loads
Our KH series is optimized to support the fastest speeds. Choose this bearing if you need seals (also comes open).
The KH series fits shafts with a max ID of 70 mm and supports max RPM speeds of 135,000 (steel) / 168,750 (ceramic).
We understand that some machine applications have different and unique bearing requirements. Some may need heavier load capabilities or faster operational speeds. We strive to offer a truly customizable approach for our angular contact bearings.

Our goal is to make sure every machine and application has the right precision angular contact bearing. If you are unsure about what bearing is best for your application, contact us!
Bearing precision is important, especially if your equipment is being used at maximum speeds. Precision classes guide the properties of bearings to ensure uniformity and regulation standards are met.
Standards are usually represented in ABEC, DIN or ISO classes.
Our in-house engineers at GMN Bearing USA offer best in class support to help you improve the performance of your application with proper ball bearing installation and maintenance. We work with several industries and applications including:
For applications that operate at high speeds, carry heavy loads, and/or require tight rigidity, angular contact bearings are recommended. Although radial bearings can be a more versatile bearing type, they are commonly used in setups where high operational speed is not required, you have limited space for bearing pairs, or axial loads need to move in both directions.
Although double row angular contact bearings are somewhat rare, they do have a place for specific applications. If assembly issues or other application constraints occur, a double row angular contact bearing may be a better option than two single row bearings.
Angular contact bearings can be lubricated with either grease or oil. For direct oil lubrication, GMN engineers can provide a small hole on the outer ring of the bearing for lateral oil supply. Grease lubrication is a similar process, except with a slightly larger hole on the outer ring for the grease supply.
At GMN, we view greasing bearings as part of the service and a key aspect of the partnership with our customers. We can grease your bearings for you at no extra cost, using a precise method to add just the right amount of grease in a clean and controlled environment. To learn more about bearing lubrication best practices, check out our Bearing Lubrication resource.
Abnormal operating temperatures can affect angular contact bearings when it comes to lubrication and the material properties of the bearing itself. Higher temperatures can cause the viscosity of the lubricant to decrease, as well as thermal expansion of the inner and outer rings, leading to increased wear on the bearing and eventually resulting in bearing failure. Mating part tolerance, meaning shaft and housing manufacturing tolerances, can be adjusted to make up for thermal effects if the application’s operating temperature is known. Standard temperatures can be handled by standard tolerances.
