The roller bearing dates to at least 40 BC, and it was applied to pulley blocks sometime in the dim past of history. There is probably no way to know when someone first put a roller bearing into a pulley block.
To lubricate a pulley, first, ensure the machinery is turned off and disconnected from power. Clean the pulley and surrounding area to remove dust and debris, then apply a suitable lubricant, such as grease or oil, to the bearing or shaft where the pulley rotates. Use a brush or cloth to spread the lubricant evenly, ensuring it penetrates into the bearings. Finally, rotate the pulley manually to distribute the lubricant before reassembling the machinery.
Pulleys have been used for thousands of years by many different civilisations. It is impossible to say who first invented them or where.
I purchased a second hand 2 color offset machine. The problem with the machine is though the condition of all the rollers is good there is an improper transfer of ink. what is the reason for improper transfer of ink from ductor roller to the first inking roller of the ink train? dear, first you check the impression setting between duct roller and first feed roller through 1 mm. thick film srtip. now the question is how you will do this? this setting is depend on type of the machine e.g. orient and manugraph. the general procedure is to set the impression that you adjust the cam or bolt both side of first inking roller. second is check the first impression roller condition.
To repair a fractional horsepower motor with bad bearings, first, disconnect the motor from its power source and remove it from its mounting. Carefully take apart the motor housing to access the bearings, then remove the old bearings using a bearing puller or by tapping them out gently. Clean the bearing surfaces, install new bearings, and reassemble the motor, ensuring everything is aligned properly. Finally, test the motor to ensure it runs smoothly before reinstalling it.
To lay cinder blocks on a concrete pad, start by ensuring the surface is clean and level. Apply a thin layer of mortar on the concrete pad where the first block will sit, then press the block into the mortar, ensuring it is level. Continue laying additional blocks, applying mortar between them and adjusting for alignment as needed. Finally, once the blocks are set, fill the joints with mortar for added stability.

To remove the bearings from the idler pulley of a 1997 Mitsubishi Mirage, first, ensure the engine is off and the battery is disconnected for safety. Remove the idler pulley from the engine by loosening the mounting bolt. Once the pulley is off, use a bearing puller or a press to carefully extract the bearings from the pulley without damaging the housing. Clean the area thoroughly before replacing the bearings if needed.
There is a website called Bearings Direct where it has a selection of different types of roller bearings for an affordable price. You will need to register for an account first before making any purchases.
Timken's tapered roller bearings have been around since 1898 so they were surely used in some of the steam powered tractors of that time.
First you take the pulley and the blade off. You unbolt the plates holding the bearing in place. Take it apart. Take the bearings off and put new ones on and put back together again.

to remove the tensioner first you need to remove the bracket that holds it. once you have removed the pulley bracket with the pulley still attached to it, 1 remove the retaining nut, and washers. 2 You will need to use a press to remove the bearing from the post.. 3 If you are replacing the bearings on the pulley you will need to remove the "C" clip retainer, and press the bearing out.
