NTN bearing units for conveyors and farm equipment
Find the NTN unit that fits your conveyor support arrangement.
NTN pillow block, flanged and take-up units, or the replacement insert alone, matched to your shaft size, mounting holes, locking method and operating environment.
- Pillow Block Units
- Flanged Units
- Take-Up Units
- Complete Unit or Insert
The first decision on every repair
Complete unit or insert only? Let the housing decide.
If the housing can stay in service, order the replacement insert. If it is worn, damaged or the mounting is changing, order the complete unit. One check keeps the order matched to the repair.
Check at the support point
Can the existing housing stay in service?
No, it is worn or changing
Order the complete unit
- Give bolt holes and housing dimensions with the shaft size.
- Choose pillow block, flanged or take-up to suit the support.
- State the locking method and operating environment.
Inside a bearing unit
Three parts work as one assembly, so quote them as one.
A mounted bearing unit combines bearing, housing and locking method. NTN Bearing Supplier quotes the full assembly, so shaft fit, mounting pattern and sealing all match the position on your line.
1Bearing 2Housing 3Locking method 
01
Bearing: match the shaft and the seal
The insert sits on your shaft and faces your operating conditions. A description by shaft size alone drops the sealing requirement, so dust or wash-down exposure belongs in the specification.
- Insert number
- Shaft size
- Sealing need
02
Housing: match the mount on site
The housing ties the bearing to your frame. Two units can share a shaft size and still differ at the bolt holes, so flanged units are quoted by hole pattern and housing dimensions.
- Mounting style
- Bolt holes
- Housing dimensions
03
Locking method: match the shaft fixing
The locking method holds the insert on the shaft. Naming it with the insert means technicians receive the correct parts together and can fit the unit without a second order.
- Set screw
- Locking collar
- Sleeve

What maintenance buyers report after delivery
Feedback from maintenance and purchasing teams on part matching, quote detail and delivery.
We run a large belt conveyor system at our grain terminal. The NTN pillow block units we ordered replaced our old mounted bearings, and the sealing arrangement kept dust out for the entire harvest season. No premature failures, no emergency replacements.
Lars AndersenAgricultural equipment fleets go through mounted bearings fast. We source NTN housed units from this supplier for our dealer network. Every unit arrives with the correct locking collar and insert, and the packaging is clearly marked so our technicians can grab the right part on the truck.
Miguel Ángel TorresWe sent a request for a take-up unit with a specific shaft size and corrosion-resistant finish. They confirmed the NTN reference and supplied the matching housing. The installation went smoothly and the unit has held up in our wash-down area.
Robert KowalskiThe price on a bulk order of NTN ball bearing units for our conveyor expansion project was well within budget. Delivery to our site in Vancouver was on schedule, and the engineer followed up to confirm the units were installed correctly.
Daniel ParkAfter a conveyor shutdown caused by a seized mounted bearing, we reordered from this supplier as a backup stock. The response was fast, the units were genuine NTN, and we now keep a safety stock on the shelf. Downtime risk is much lower.
Ivan PetrovWe compared three suppliers on a list of NTN flange and pillow block units. This one gave the most detailed quote, including the insert bearing part numbers and housing material. The order arrived complete, and our maintenance team had no questions on receipt.

FAQ
NTN bearing unit questions from the shop floor
Should I request a complete bearing unit or a replacement insert?
Request a replacement insert when the housing can stay in service, and a complete unit when it cannot. A worn or damaged housing, a changed mounting arrangement or a new support point all call for the complete unit. Specify inserts by shaft size and locking method.
Which mounting measurements are needed for an unidentified unit?
Measure the shaft size, the mounting bolt holes and the housing dimensions, then note the locking method. Add a clear photo of any markings on the housing or insert. Gaps in the identification are cleared with you before you accept a quote.
How should I describe a dusty or wash-down environment?
State the exposure directly in your enquiry, such as grain dust or a wash-down area, and mention any sealing requirement from the original specification. Sealing depends on these conditions, and a shaft size cannot convey them.
Can drive bearings and shaft-support parts go on one enquiry?
Yes, drive bearings and shaft-support parts can be combined in one parts enquiry. This works for a single repair or for a complete conveyor or production line. List the quantity for each item.
