The support rails define a set of holes aligned coaxially with each other. A bearing block is arranged on an intermediate one of the support rails. The bearing block includes a base strip defining a groove extending in a longitudinal direction along a lower side, and defining a hole extending in a lateral direction. An upper portion of the intermediate support rail is disposed in the groove and the hole is aligned coaxially with the set of holes in said support rails. A plurality of bearing supports extending from an upper side of the base strip. Each of the bearing supports defines a bearing surface extending in the lateral direction. Adjacent ones of the bearing supports are spaced apart from each other in both the longitudinal direction and the lateral direction. A support shaft extends through the hole in the bearing block and the corresponding set of holes in the support rails. ## Claims ### Claim 1 A bearing block for a roller conveyor, comprising: a base strip defining a groove extending in a longitudinal direction along a lower side of said base strip and having at least one hole extending there through in a lateral direction; and a plurality of bearing supports extending upwardly from said base strip, adjacent ones of said bearing supports being spaced apart from each other in said longitudinal direction and being offset from each other in said lateral direction, and each of said bearing supports defining a bearing surface extending in said lateral direction. ### Claim 2 (depends on 1) A bearing block according to claim 1, wherein each of said bearing supports defines a hole extending therethrough in said lateral direction to form said bearing surface. ### Claim 3 (depends on 1) A bearing block according to claim 1, wherein each of said bearing supports defines an upwardly facing recess extending in said lateral direction to form said bearing surface. ### Claim 4 (depends on 1) A bearing block according to claim 1, wherein alternate ones of said bearing supports in said longitudinal direction are aligned in first and second longitudinal rows, respectively. ### Claim 5 A bearing block for supporting a plurality of rollers in a roller conveyor, comprising: a support rail having at least one hole; a support shaft; a base strip defining a groove for receiving said support rail in an assembled position, said groove extending in a longitudinal direction along a lower side of said base strip, said base strip having at least one laterally extending hole to be aligned with a corresponding said hole in said support rail for receiving said support shaft in said assembled position; and a plurality of bearing supports extending upwardly from said base strip, adjacent ones of said bearing supports being spaced apart from each other in said longitudinal direction and being offset from each other in said lateral direction, and each of said bearing supports defining a bearing surface for receiving a roller shaft, said bearing surface extending in said lateral direction. ### Claim 6 (depends on 5) A bearing block according to claim 5, wherein each of said bearing supports defines a hole extending therethrough in said lateral direction to form said bearing surface. ### Claim 7 (depends on 5) A bearing block according to claim 5, wherein each of said bearing supports defines an upwardly facing recess extending in said lateral direction to form said bearing surface. ### Claim 8 (depends on 5) A bearing block according to claim 5, wherein alternate ones of said bearing supports in said longitudinal direction are aligned in first and second longitudinal rows, respectively. ### Claim 9 An arrangement for supporting rollers in a roller conveyor, comprising: at least three support rails arranged parallel to each other, said support rails defining at least one set of holes aligned coaxially with each other; a bearing block including a base strip defining a groove extending in a longitudinal direction along a lower side of said bearing block and having at least one hole extending in a lateral direction, said bearing block being arranged on an intermediate one of said support rails such that a portion of said intermediate support rail is disposed in said groove and said at least one hole is aligned coaxially with a corresponding one of said sets of holes in said support rails, a plurality of bearing supports extending upwardly from said base strip, adjacent ones of said bearing supports being spaced apart from each other in said longitudinal direction and being offset from each other in said lateral direction, and each of said bearing supports defining a bearing surface extending in said lateral direction; and a support shaft extending through each of said holes in said bearing block and the corresponding one of said sets of holes in said support rails, respectively. ### Claim 10 A roller conveyor comprising: at least three support rails arranged parallel to each other, said support rails defining at least one set of holes aligned coaxially with each other; a bearing block including a base strip defining a groove extending in a longitudinal direction along a lower side of said bearing block and having at least one hole extending in a lateral direction, said bearing block being arranged on an intermediate one of said support rails such that said intermediate rail is disposed in said groove and said at least one hole is aligned with a corresponding one of said set of holes in said support rails, a plurality of bearing supports extending upwardly from said base strip, adjacent ones of said bearing supports being spaced apart from each other in said longitudinal direction and being offset from each other in said lateral direction, and each of said bearing supports defining a bearing surface extending in said lateral direction; and a support shaft extending through each of said holes in said bearing block and the corresponding set of holes in said support rails; a roller shaft arranged in engagement with each of said bearing surfaces, respectively; and at least one roller sleeve mounted on each of said roller shafts.
