If you are referring to an internal combustion engine they are also called the 'big ends'.
These are the bearings on the crankshaft and connecting rods, the bearings on the other end of the connecting rods are the 'small ends'.
Bearings help machines work smoothly and keep gears and machines that need bushings (with bearings in them) from wearing out too quickly. Bearings significantly reduce friction in working machines (with the help of a bit of oil and grease), thus reducing wear and tear--and reducing maintenance costs and times of repair.
The big end bearings torque specification for the QD32 diesel engine is typically around 50 Nm (37 lb-ft). However, it's important to consult the specific service manual for the QD32 or manufacturer guidelines, as torque values can vary based on the engine's production year or revisions. Always use a calibrated torque wrench and follow the recommended tightening sequence to ensure proper installation.
Generally, journal bearings have higher friction factor, consume higher energy and release more heat, but they have larger contact surface, so normally used in low speed high load applications.
To replace the front wheel bearings on a 553 skid steer, first, lift the skid steer and securely support it on jack stands. Remove the wheel by taking off the lug nuts and then detach the hub assembly. Remove the old bearings and races using a bearing puller, clean the hub, and install new bearings with a suitable press or hammer, ensuring they are seated properly. Reassemble the hub, reinstall the wheel, and torque the lug nuts to the manufacturer’s specifications.

The bottom bracket noise on your bike could be caused by loose bearings, worn-out bearings, or a damaged bottom bracket shell. To fix it, you can try tightening the bottom bracket, replacing the bearings, or getting a new bottom bracket shell installed by a professional bike mechanic.
I have a 1997 mule 2510 You have to remove the whole rear end of it to replace the rear bearings because the bearings are inside the housing on the cv joint. The axle bolts in the rear diff with six bolts. you take the shocks and springs and all loose and drop the whole rear end and the and take the top part of the axle off the bottom half axle and then you will see the bearings
Rear end differentials have several different types and sizes of bearings. The cost to replace all of the bearings will be around $400.
On a 2stroke engine the oil/gas mixture enters the crank case (lubricating the crankshaft bearings) before it is drawn into the cylinder.
0:1 it has a separate oiling system for the bottom end and will spin bearings if not used. make sure to bleed it the two oil lines down that have the banjo fittings on them or it won't provide enough oil to the bearings.
To maintain bicycle bottom bracket bearings for optimal performance and longevity, regularly clean and lubricate them, check for wear and tear, and replace them when necessary. Keep the bearings properly adjusted and avoid over-tightening the bottom bracket. Additionally, protect the bearings from water and dirt by using appropriate seals or covers.
Which differential bearings? Pinion bearing? Carrier bearings? End axle bearings?
the big end bearings torque down at 55 - 65 Nm
You can remove bearings from a BMX frame with a 'mid' bottom bracket without damaging them using a 3/8s rachet extension.
To install a press fit bottom bracket, first ensure the frame and bottom bracket are clean. Then, press the bearings into the frame using a bearing press tool. Finally, insert the spindle through the bearings and secure the crankset.
Your top end consists of piston, rings, wrist pin and bearings and clips.
By "siezed", I'm guessing that the crank bearings froze. If that's the case, either a complete rebuild (no sense pulling it out and fixing the bottom-end without doing the top end also) or a new or remanufactured engine
