FRANTZ built its conveyor bearing reputation on the quality and performance of its Commercial grade Unground Non-Precision bearing assemblies for conveyor rollers. FRANTZ non-precision conveyor bearings have served customers well in sprocketed rollers for Chain Driven Live Roller (CDLR) applications. There has also been increasing use of GenStar® Precision conveyor bearings in these applications. FRANTZ has solutions for customer CDLR bearing challenges.

This is our Sprocketed CDLR Bearing & Roller Solution value to you:

• Mount bearings after welding the sprocket

While mounting bearings into tubes before welding sprockets to the roller assembly works well for all metal non-precision conveyor bearings, the intense heat distorts polypropylene isolator sleeves that provide precision bearing assemblies with their cushioning quiet characteristics. Therefore assembling sprocketed CDLR rollers with precision conveyor bearings once was a challenge for conveyor manufacturers. FRANTZ engineers have developed a solution to this problem. Tooling is now available to insert and swage GenStar^® Precision Conveyor Bearings into 1.9”, 2.5” and 3.5” rollers after the sprocket has been welded to the roller, providing a GenStar^® Precision solution to CDLR bearing applications.

Additionally, FRANTZ custom swage tooling can crimp the bearing even when the sprocket is a minimum of 5/16” from the end of the tube.  FRANTZ fields numerous calls from conveyor users stating the press fit bearing has ‘walked’ out of the tube in CDLR rollers.  Additionally, we know that under extremely heavy loads or in high impact areas it is possible for the bearing to walk loose as well. Why press fit when you can swage fit as FRANTZ custom tooling assures a secure fit, especially in those situations where the sprocket is positioned close to the end of the tube whereby only a press fit bearing has been commonly used.  Unique hydraulic tooling crimp rings are available for the following roller tubes:
- 2-1/2”, 11 ga. (bearing models 1970, 2550 & 5000 series)
- 2-1/2”, 11 or 12 ga. (bearing model 2570 series)

• Variety of CDLR bearing choices
  In addition to the GenStar^® Precision Conveyor Bearings referred to above, FRANTZ offers conveyor manufacturers rugged and dependable GenII^® Semi-Precision Conveyor Bearings and Commercial Grade Unground Non-Precision Conveyor Bearings that can withstand the abuse that heavy pallets and drums inflict on CDLR conveyor components.


• GenII^® Semi-Precision Conveyor Bearings designed with tough IronGrip carbon steel housings and superior quality ball complement can comfortably carry significant loads and withstand heavy abuse. Click for further information on GenII^® Semi-Precision Conveyor Bearings.


• In the area of Commercial Grade Unground Non-Precision Conveyor Bearings, FRANTZ offers two outstanding choices. FRANTZ engineers have designed the Power Swage bearing series that provides further gripping strength for CDLR applications. Click for further information on our Power Swage Conveyor Bearings. Our sturdy Radial Thrust Conveyor Bearings in particular are good candidates for curved CDLR applications. Click for further information on our Radial Thrust Conveyor Bearings. Non-Precision Conveyor Bearings have the lowest co-efficient of friction allowing for a lower starting torque and thus minimizing the necessary hp of chain drive motors. FRANTZ offers a variety of optional features for conveyor bearings used in CDLR applications. Click for information on Regreasable Conveyor Bearings and Straight Faced Conveyor Bearings.


• Let FRANTZ manufacture CDLR Rollers to your specification
  Whether made with single or double sprockets, CDLR Rollers can be a challenge to manufacture. If you need the entire package, FRANTZ will deliver a quality product customized to your specification.
