Mounted Ball Bearing Installation Manual
Mounted Ball Bearing Overview/Seltection
Ball Bearing Interchange chart

In most situations there are four methods of attaching mounted ball bearings to a shaft, these methods include using set screws, eccentric locking collars, tapered adapterors, or using a clamping lock collar. We stock all four attachment components, our housings are made to support any choice of attachment component.

Mounted Ball Bearing Locking Methods

SET SCREW LOCKING-UC INSERT
Set Screw Locking is one of the most popular and the least costly of the 4 attachment methods. This simple install involves two set screws squeezing the bearing onto the shaft. This methed is used for low to medium speed applications. The set screws over time create a small burr on the shaft making removal a little more difficult, and periodic retightening of the set screws is required. A knurled or cup point design in a set screw will help keep it tight.
ECCENTRIC COLLAR LOCKING-HC INSERT
The eccentric locking collar is also a popular method of mounting a ball bearing to the shaft. The bearing inner ring has both an eccentric groove and a mating groove machined into the collar. Commonly a drift pin and hammer are used to tighten the collar against the bearing to the shaft. The collar is tightened with the direction of shaft rotation.
CONCENTRIC LOCKING CLAMP COLLAR-CL INSERT The Concentric Locking Method allows the inner ring of the bearing to fit concentrically onto the shaft. This being an inner ring to shaft clearence fit, makes for easy installation, and does not loosen after proper initial tightening. This is slightly more expensive than other methods due to the additional collar and slotted inner race. When the cap screw in the split locking collar is tightened, the collar Squeezes the spline zone of the inner ring to grip the shaft. This method is easier to remove and lasts longer than the others mentioned.
ADAPTER MOUNT LOCKING-UK & GSR Insert The adapter locking method provides the most concentric locking capabilities of all four locking methods. This method simulates the direct mounting of bearing to the shaft. This adapter method allows for the highest speed, and least amount of vibration. It is higher in cost compared to the set screw and eccentric locking types, as this locking unit is engeineered using more components, however its advatages are obviously superior. Near perfect shaft fit allows for no fretting between components when they are properly tightened. This bearing will also allow you to reuse the orifginal shaft.

These units are built robust to handle heavy loads at both high and low speeds. These housings will accommodate both grease and oil lubrication. Seal options allow for the most challenging environments. These Blocks comes with industry standard mounting, and shaft center height dimensions. The new solid base housing had made these blocks some of the most robust blocks available on the market. The design includes an internal oil cross-port channel to ensure equal oil levels across all rollers of the spherical bearings. If high speed is a requirement, double row ball bearings are your best option. For circulating oil systems, drain holes are standard on either side of the block. The drains accept standard oil site glasses. The SAF's housing caps and bases are paired to ensure a precise bearing fit; hous-ing match marks are standard. The bearings are easily accessed via the large pry slots.

Metric Sprocket Dimension Overview
PTI Metric Sprocket Types

TL Taper Bushed Metric Sprockets
PTI TL Metric Sprockets

TL Sprockets are available in a wide range of diameters for various requirements, and the speeds associated with these applications. Sizing of the TL sprockets include: ISO 06B, 08B, 10B, 12B,16B and 20B chain sizes (3/8 to 1-1/4” pitch) for single, double, and triple chain set-ups. These sprockets are mounted using industry standard TL tapered bushing series: 1008 thru 5050 (up to a 5 inch, or 125 mm shaft diameters). The most popular sizes are in stock, and come standard with hardened teeth. The C45 sprocket's steel construction, allows for induction hardening of the teeth making it stronger and more robust. All sprockets are available with the induction hardening process upon request. The TL Taper Bushed Sprocket provides a true concentric fit. As the bushing screws are tightened, the bushing squeezes around the shaft for a tight fit. Standard hex wrenches are the only tool required for installation or removal, these wrenches are sold separately. The screw can be reused if removal is needed, can then and threaded into the bushing's removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and inch bore TL bushings all of which are industry standard, and global design. This makes the TL sprocket is so versatile. The TL sprockets are suitable for higher speeds and heavy loads. They are ecenomically priced, making this sprocket the popular choice for new designs and replacements. TL sprockets are less expensive than custom or finished bored sprockets.

PTI TL Metric Sprockets Offerings

HB Type Metric Sprockets
PTI Hub Type Metric Sprockets

Hub Type Metric Sprockets are available with a minimum plain bore also known as a pilot bore. Due to our custom bore, and keyway machining capabilities, all bore sizes are available. Usually Hub type sprockets are attached to the shaft using a clearance fit held in place with two set screws and a keyway. Clearance fits are a popular choice for lighter loads, and slower speeds. A press fit also known as a shrink fit, are the preferred choice for higher speeds, and heavier loads as they are more securely fit to the shaft. Depending on the shaft fit clearance, these sprockets may cause possible fretting or shaft wear over time. PTI stocks all standard hub sprockets. Optional hardened teeth are available upon request. Press fitting usually requires the sprocket to be heated for installation to expand the bore. Upon cooling the sprocket shrinks and is tightly secured to the shaft. The shaft key is secured using the supplied set screw.
